I picked up a Sherwood S-7200 today at a thrift store, brought it home to realize that it was missing all the fuses on the back. This is my first vintage amp so I don't know much about replacing fuses or where to buy them. I'm guessing Radio Shack? What would I ask for, the only information I can find is that it says 3A, but a google search for 3A fuse comes up empty, and I can't find any information on fuses for this receiver. I'm hoping these are laughably easy questions! Thanks for any help you could give a rookie!

Write to Sherwood and give them your model # (http://www.sherwoodusa.com/product/list.asp).
If they won't give you the fuses free, they should tell you what you need or sell them to you. Amazon sells many different size fuses cheaply...
Give them to you? Wow, what company will do that for a unit over 30 years old. Even McIntosh is not that good at support. Also, suspect the company can not supply the information nor have a replacement part.
Volvo until sold had and could supply parts going back to the PV544 but doubt any audio company can do that in terms of support.

I have dealt with a few companies. Usually they are very helpful. The worst is Cerwin Vega. The best I have dealt with was Definite Tech. They would gladly give you fuses. If they did not have the part to sell, they would tall you exactly what you needed.
I suspect the Definite Tech subwoofer you run, if memory serves me right, is a lot newer than a 7200 and even maybe either still under warranty, in production or woarranty ran not that many years ago.
I know nothing about C-V other than I never liked their speakers. What was your experience with them.
Koss, maybe has the best reputatin for customer service starting in about '88 or '89 when it instituted a true lifetime guarantee made and sold after a date certain. While the written requirement is to be the original purchaser and submit a copy of the receipt it appears it is not enforced and a number of flea market buyers of their phones send them in with the return postage fee from what I understand. My phones, sadly were exempted from the warranty for though made after the date, were out of production one offs from their last remaining parts. But other than pads that are available for about $5 for the pair from them, mine have never needed servicing.
The worst in my experience is Eton that now owns Grundig. No service manuals, no service, no parts sales to repair shops. Only honors warranty from registered dealers and there appears to be either none or almost none in actual existence and the registered dealers do not seem interested in selling the product. I have a pair of their radios; one for use and another for backup.
During the warranty period a number of companies would send small parts at no charge or even send replacement parts on exchange to an owner or repair facility. Out of warranty fewer will send small parts to customers for free unless there were production issues. This happened with the original ADS L300 that used a foam surround. The foam disintegrated seemingly just after the warranty ran. By that time they had discovered the issue and the newer model had the same woofer with rubber. When mine let go I was offered either woofer at no charge and decided on the newer. McIntosh and a few older companies used to have silent recalls. When a unit was sent for repair either to the company or a factory authorized repair shop along with the repair changes or mods were done to correct some deficiency that was put into later production runs. When persons get some manuals these technical bulletins may be included or there may be multiple service manuals based on the serial numbers of a production run. I have a Sherwood receiver that has a manual and they issued both addendum sheets to include with it related to the later production changes and also complete manuals related to the production run changes. The receiver I have has 4 manuals depending on the s/n. Sherwood was notorious for this as the company seemed never to change model numbers. My Sherwood SS tuner has 3, actually 4 versions with over its life a substantial and material design and production change but the model number never changed nor a series designation added.

My DT subwoofer is not under warranty nor still in production. They sent many things I needed. Even a new driver at no charge. The reason I suggested he call Sherwood is that he was unsure just what he needed and did not know the fuse sizes. It certainly would not hurt to contact them first. They have a contact # and an email site. I have done many repairs over the years and that is where I would start..
As for CV.....they are like many speaker companies. Their products look nice on the outside but are built very poorly when you look further. They were bought out by a larger parent company (Gibson guitars) who don't seem to care about them AT ALL. And I think Kimball pianos. Now Atlantic tech is just the opposite...the deeper you dig the more impressed you will be. My 12" subwoofer has a 9.5 pound motor (voice coil and magnet structure). I am not sure how low in frequency it goes but I would guess 20hz. M&K and KEF are the same way from what I have seen along with others yet to be seen by me.
C-V way back in the beginning had a reputation for having a nice looking product voiced for instant sales while the cabinets and drivers were trash. Many early dealers bailed within the 1st year and we had a ton of them come in for trade by the college crowd, most with blown drivers and stories that when they tried to get warranty work, it was always being refused based on the speaker was abused and reasons given like the amp was too small and clipped or too large and burnt the voice coils out. We contacted them to see about buying replacement drivers and told their policy was not to sell the divers aftermarket and if a set was bad under warranty the dealer was supposed to replace the set and send in the s/n for a credit. Tech carried the line for a time when I was in management and they finally issued instructions that if a set was sold by Tech and came in for warranty repair we were to make up a story that it had been found they were not reliable (which they were not) and give a full credit towards another set of speakers. The credit was based on the system discounted price but, if the customer was not happy to with the value to just give a credit for the price the store would have charged if the customer had bought the speakers with no system.
Tech had a real isue with them and took extraordinary remedies in this case to satisfy the customers. Not sure how bad a hit they took, if any. I suspect they simply ordered a load and offset the bill while wholesaling the order to someone like Crazy Eddie and told C-V to pound sand. When I had my stores we ran into a similar situation and finally handled it this way when we could not get the company to come to terms. However, it was not C-V in my case.
After the sale company support can be as important or even more so than the initial sale. Sadly companies tend to start understanding this and eventually lose sight of it. Look at McIntosh, for example.

I'm looking at a picture of the back of this and it looks like there should be 3 black parts going into the power and speaker fuse spots. They are missing, I'm guessing those house the actual fuse? Where would I be able to get a hold of those?
As mentioned below, Radio Shack will have the fuses. They also sell the fuse holders - or they did the last time I went. Definitely no need to write to Sherwood.
You're probably not missing the bodies of the fuse holders, just the caps. .You need to inspect the body of the fuse holder on your Sherwood to see if the outer lip area has screw threads or not. Then compare it with the type sold at RS. The bayonet type doesn't have threads.
Re: the comment about it not being a good sign . . . it certainly means that the thrift store was unable to test the unit before selling it. Do they have a return policy?
The reason why they might be missing is of greater concern. Best scenario is that the previous owner needed them as replacements for some other equipment or perhaps they got broken when something smashed into the back. Worst scenario is that there is a more serious problem and they were intentionally removed, either after they kept blowing or, as a safety measure, to prevent it from being powered on. Old time techs also sometimes cut the power cords or plugs off gear when there was a serious problem.

Cool, I'm glad that Radio Shack would have the caps. It's a screw on type. If it doesn't work, I'm only back $10 and whatever the parts cost which I'm seeing is somewhat of a steal for the 7200. Thanks for the help!
Would I be able to get the caps on Parts Express and if so what would I need knowing that it's a screw on cap?
Check around, but I don't know if anyone sells just the caps. You may have to buy the entire fuse holder. If there's some place local that has a bunch of broken equipment you might be able to scrounge a few caps at no charge.

the reason I recommended calling Sherwood is that sometimes manufacturers will give small things like this free...at least the better ones do. it might help to have a users manual too to be sure you get everything right.
I don't remember if they're screw in or bayonet caps -- they're fairly standard, those two. I can check if someone else doesn't weigh in (and/or if you can't tell yourself).
The "3A" fuse you need is bog-standard. The 3A means a rated current of 3 amps. The size/style of fuse you need is (almost certainly) is called "3AG". The link below is an example; you can probably even still find 3AG 3A fuses at your local Radio Shack (although the staff there may or may not know that they have 'em...).
