Are the EL84 tilted at a 45-degree angle?, posted on April 8, 2014 at 02:10:16
Is that bottom left one a Telefunken? Wonder what's the philosophy with tilting the output tubes?


Thanks!

Wow! I have several Sherwoods and I thought I'd seen all the variations, but not these. Sherwood was definitely a company where the engineers seem to have had more influence than the marketing department.

I think the purpose of the tilted tubes was to reduce the height of the cabinet. Probably considered a more "modern" design element which helped them to stand out a bit in comparison to other brands. Another example would be their white faceplate. They were kinda like the Apple of the tube amps in terms of their design.

are the reasons for the angled tubes..We know heat rises and tubes being toward the end of the cabinet on an angle is better than having them upright to where the heat would be contained inside the metal cabinet trapping it in.

It looks like it is a mono amp. I have a similar Bogen amp. How many 7189's a side?

Why not have the tubes placed horizontal? Then, you'd have the most vertical clearance. I know many guitar amp combos have this arrangement.

Just curious. Thanks!

Mike,

You will have to tell us how it sounds after you restore it.It's interesting that rare old gear is still turning up.

New one on me. I thought the mono S1000 was their first commercial home audio amp.

Considering the script on the front for the word "Sixty" I wonder if this was maybe a pre-production prototype, though it otherwise looks like a finished product. Mike, can you post a shot of the green label, I'd be interested.

The angling of the tubes was in addition to reducing the height of the amp has been suggested it dissipates heat better and faster than a vertical layout as it presents more of the tube surface to the air flow from the bottom. The heat shield is part of the design creating a chimney and directing the air and not simply as either a tube protector or support for a cover or wood sleeve.

Can you post the measured specs after going through it; Sherwood was a might inconsistent with its ratings, sometimes a might optimistic and other times a might too conservative.

That would be ok but the one I showed in the picture belongs to a friend of mine that I rebuilt a citation 2 for.He became a friend after I rebuilt and modded a few things for him..If you think my collection of 281 tube amps is a lot,he has over 700 tube amps and counting..He rebuilds a lot of his own stuff now and even tho he is in Tracy Calif,I was able to teach him stuff via Skype.It worked out very well..BTW,mono amps are counted as one amp so that's why our collections may appear more numerous.

My name is Mikey and I am a tube amp-aholic. Methinks you are beyond a 12 step program. :-)

It depends on the speakers or my listening mood at the time..The reference system which is in the house next door in the basement are the Martin Logan CLXs power with the McShaned Deuces or I put the Altec 1570s on them with the Tutay mods.The Deuces I run at 4 ohms in parallel effectively giving me 2 ohms and they are biamped with the Descent subs.
I haven't been listening to the Logans lately because I spend all the time in my family room where the ribbons are and on those, I run the Mc275 or the Eicos or a single Deuce or an Mc240,all of which have the McShane upgrades and they all loaf effortlessly on these speakers.
I love all tube amps and even tho I have my favorites,I've been playing with a lot of integrated amps lately.
I took on a philosophy 7 years ago after I started building my amps the way Jim McShane suggested.This worked on the Macs and Eicos as well as the Citations of course and then,I added a couple tweaks of my own for added measure with the poly filter caps, Schottkys,and maybe a choke.The Schottkys were actually Eli's idea as was the hash filter that I added to the Macs which the Mc240 really likes..The idea was to build the best reference system I could with the Deuces and the Martin Logans. I would then build every amp,preamp,or integrated amp to come as close to the sound of my big system as I possibly could..Now naturally I don't expect it to have the purity of the CLXs with the Deuces,Macs,or Altecs, but I try to at least make whatever I rebuild sound correct with the lowest distortion and best dampening and so far it has worked out well.The preamps with Jim's upgrades are the other part of the equation.

And I thought I had a lot of amps. Mike, how do you keep all those amp's electrolytic caps formed? Do you stick them onto a multi-outlet and have dummy loads?

I try to play all my guitar amps, at least once every six months. For a good hour or two. Anything in storage (like the 1947 Model 26) gets ramped up once a year.

I can imagine the heat of 100 amps, at idle.

Many in my amp collection I haven't rebuilt or recapped yet..The main ones I had already built and used I take out and play every 4 months.

Let's hope that our hearing remains good as long as possible.You have a lot of amps to listen to and enjoy.

Even so, 350 tube amps is more than any store back then or now would ever have in stock. Would love to see photos of the collections.

281 not 350..I have put pictures of them on thru the years..Much of my amp collection are duplicates of Dynaco MK3s, St70s,and Heath W5Ms..Those three models make up 88 amps.

Mikey, That looks just like my first amp. My Sherwood was only 36 watts and mono of course.
I bought it new in 1958 while I was in the Army and stationed in what was then West Germany. The
Military got some kind of deal like 50% off. The rest of my first "Hi Fi" system was A WHARFDALE
SFB-3 SPEAKER (LOOKED LIKE A QUAD 57) BUT HAD DYNAMIC DRIVERS WITH AN UPWARD FIRING TWEETER. MY RECORD PLAYER WAS A GARRARD RC 98 CHANGER WITH A GE CARTRIDGE.THE SFB 3 could probably hold its own with many current speakers today.
Thanks for the memories
