Besides the 'bay, where would I be able to find a replacement bracket?

I bought a Citation II finally for a cheap price, but it was someone's project on P2P wiring, and when they recapped the PS section, it looks like they added another transformer, ( maybe an earlier bias mod?) they also modded v1 and V4 to 5691's(I can not find ,through any searches where this mod was accomplished and the reason's why) and V3 and V5 are 5687WA's.....

Also there were other mods, I'm assuming these toggels on the top are for the 5691's, or maybe a UL/triode mode switch, also an additional set of fuses on the top, just above V8 and V9.

I will post pics later, I'm sure everything thing I wrote/typed will be better explained.

It looks like I'll be giving Mr. McShane some business and emails in the near future.

Thanks all,

-chris

 I'm interested in the same item for the same reason. I bought a Cit. II about 8 years ago because it had NIB KT90s and 12by7s. A great deal, worth it just for the tubes.
Now I would like to bring it back with GL KT88s. All help is appreciated.
Please help Mr. Oface first though, I did steal his thread.

 Wondering if anyone has the measurements/dims and drawings of that ps plate? I have a friend that could get it done for cheap......

 If you didn't sell the KT90s off, use them. The "reissue" GL is the best tube currently being produced to use in a Cit. 2. However, type 2 and early production type 3 EI KT90s are the best tube to use in a "Deuce".

 You need a PS bracket and the terminal boards to put the amp back together. I don't have a bracket nor do I know of anyone who can supply a dimensional drawing to have one made. The bracket also serves to reinforce the chassis top deck to prevent the 15 pound power trafo causing it to sag.

IIRC you can buy "hole shrinkers" to allow use of a 9 pin socket where the 5691s are now. Why were they installed instead of the 12BY7As? Well, everybody knows that pentodes are no good, right? :-)

Maybe it's my old eyes but I don't see any toggles on the top deck. I DO see replacement pots in the holes where the AC balance pots were originally.

I would try to save those old yellow Rel-Caps, i still think they are a fine cap. They are probably polypropylene.

You've got a lot of work ahead of you, but when it's all done you'll be very glad you did it!

 AA sponsor Bottlehead offers them. See the link provided below.

You can make them yourself from sheet metal. Cut rhombic shaped pieces whose long dimension fits Octal socket mounting centers. The short dimension fits Noval socket mounting centers. Punch a hole in the rhombus that fits the Noval socket.

 Thanks for replying Jim.

I'll take some better pics with a better camera and post them later.

I assumed that without the PS bracket that the chassis has/will sag.

I'm going to keep my eyes open for a bracket.

I have a Cit. II running KT90s already. It's fantastic!
I'm looking for different flavor, I have chocolate already.

 Coincidentally someone on the bay has a bracket for sale with "upgraded"
lytics. Kinda pricey though.

 Are the turret boards for the Citation II specifically "circuit boards" made for the Citation II, or can I make my own? Like these, I'm not affiliated with this seller....


Thanks,

 Mike Samra has a factory built "Deuce" in for servicing. A link is provided below. Maybe you can get him to photo the PSU bracket in combination with a scale, to give you a decent idea of how to proceed. Of course, detailed measurements would be VERY nice.

Speak sweetly. ;>)

FYI - that is one of my early PS kits installed on the bracket. So if you think my kits are okay it might be a better deal. The inrusk limiter strip and the large Panasonic film caps are installed poorly or in the wrong location, and the snubber cap for the diodes is missing; but that's all easy to fix. See the picture above for a nicely built bracket.

However he is getting what amounts to $100+ for the bracket by the time you deduct the kit cost. That's assuming no cost for labor to instal the parts though. So overall it isn't such a bad deal.

If an inmate grabs this bracket I'll be happy to help them bring it up to full speed.

Note that I have no known connection to the seller whatsoever.

 

I'm curious how that unit sounds with the mods it has as far as the tubes go?, posted on July 8, 2016 at 12:37:22

 I don't know if you got to listen to or not but if you clean up and paint the transformers,you may be able to sell the unit and get a more suitable rebuild candidate because like Jim said,you have a lot of work ahead of you if you want to make this a McShane super amp.That bracket for 250 I don't trust because we have no idea how old those caps are and if they were hooked up backwards and even if they weren't,the shelf life comes into question.If someone has a bracket you can get or you can make one,then you would be better off. Jim can hook you up with the wire harness and you can source turret boards pretty easily.You do have the problem of the larger holes for the 6SL7s but that can be solved.

 Ahhh! I was talking to him this morning. If he has it available in a couple of weeks, I plan on purchasing it from him.

I'm going to gather the manual, and other information on the amp, plus paying your website a few more visits too!

I'm gonna be doing the work, so I'll save on labor costs at least, I like making a budget and sticking with it, or close to it!

Off to search and download materials....

 Ahhh...

I haven't even plugged this amp in yet. Just out looking, researching and going to take my time, but the Im not going to throw gobs of cash on this thing. I'm no soldering maestro, but I come from a tech background with experience with soldering and electronics, so I'll save on labor there.

Yes Mr Samra, I've considered using this amp as a step and using the proceeds to get a better one. My friend who can make the bracket, asked questions, he said send him the dims for the top chassis too.The front is in pretty decent condition.

I have a feeling this wasn't the first mod installed. I'll take better pics, with better lighting, camera, etc and show the work one the inside.

I'm very curious too as what this things sounds like as is. Just not gonna hook up my 19's straight away! Lol! I do have some shop speakers I can plug in, but my gut feeling tells me not to do that yet. I fear some issue to make an opt fail, and I don't want to shell out for those!

I need to down load the manual, and research and sell some stuff that's been sitting around too long unused and tackle this bit by bit...

I plan on having some more pics up, a gentleman email me and said he will take measurements, but someone dimed you out and said you had a factory deuce in. If you have a minute, you wouldn't mind taking a few measurements of that bracket please? If would really appreciate it!

I'll take some pics and post them later.....
Thanks!

 If you have Altec 19s,they are a lot of like ESLs and Magnepans in the sense that they love wide bandwidth amps with low distortion so they can strut their stuff.

Its 12 and 3/4 long and 2 and 3/4 deep but what I'm going to do is pull off the bracket and draw a template and mail it to you..I will pull the cans off and trace the bracket onto some paper;

 Also the holes for mounting the caps are 1.375" diameter except the one for the old bias cap which is at the opposite end of the bracket from Mike's picture. But I'd make it the same size as the others since modern clamp mount caps caps fit well with those size holes.

 Thanks for the diameter measurements Jim!

Mike said he'll send me a drawing of the bracket, I think that and the measurements should be good for my friend.....

Thanks again all!

 Make sure the bracket is thick enough, and also make sure you look carefully at the picture I posted for where the clamps mounting holes go along with the other holes in the bracket. The same goes for the bracket-to-chassis mounting holes.
