Of course,this is mostly cosmetic.

I saw that thread. To each his own, but why on earth would you put the leads in the little holes on top of the turrets. A much better mechanical joint is formed by wrapping them around the turrets.....my 2 cents....
BTW, I have rebuilt 36 of them at last count.....and can do one in my sleep now...

I don't agree with the guy is doing it either as I don't make physical mods to vintage gear.I was more or less showing the tear down and what is involved in a complete make over.He is also reusing a lot of old resistors and I don't believe in that either,at least the CC that have been heated up on disassembly.

Yeah Mike, I agree. I don't reuse the big power resistors either. They used to measure on spec, but I am finding more and more that are over 10% out now that they are 50 years old. Depends on who built the thing originally and how well they soldered. I also replace all the board jumpers and the ones under the boards as well. Why not? You have it apart and you can make it reliable for another 50 years....
When properly rebuilt there is no finer amp...only other really good amps that are different.

As cheap as new resistors are,there is no sense in reusing the old ones although,the power resistors in the deuce are excellent.I reuse those at times.

what would be a good replacement for those resistors? thanks.
I have put together complete kits if you need them, or I can provide single pieces of the resistors you need.
I use a variety of types/brands. For the large power resistors I use wirewounds of slightly larger wattage than the originals.
Thanks, I'll look you up when I am ready for the rebuilt.
Jim McShane reccomends keeping the big "glass" power resistors in the Citation II if they're still good. Those, the trannies and the chassis are the only original parts left in mine.
I hear ya Bob.Those were top quality resistors and still are to this day.You will notice that they have the vented end on them which is great for cooling.

The previous owner of my Citation I did that, too, and I've been itching to redo it correctly.
Hi
If you are going to work on it I can give you a number of tweaks when you are ready. The McShane power supply will really make a difference and there are a number of key resistors in the signal path that will wake it up a bit.....if they haven't been replaced.
cheers,
Don
Thanks, Don -- I already installed a McShane power supply ... I just never got around to changing to the resistors and capacitors, since they are at least of decent quality (Panasonic film caps and metal film resistors), despite being strangely installed. Some day I will take it apart again and tidy up the boards. But it's hard to justify when it works fine as a daily-driver!

Try some k40s in place of the .22s.I use them in place of the .47s also.Jim carries those caps but it makes a hell of a difference.

Hi Jon,
If the caps are those Matsushitas that Jim sells there is no point in finding anything else for a Citation I. They are very good. Try changing the 220K carbon resistors where the volume pot lead enters the board. If they are the originals you will make it sound better by using a good quality carbon film there. I like the Takmans, but there are other good ones. Also the 47K resistors of the tape monitor switch are in the signal path. Put another good carbon film there. The RIAA caps and resistors on the rolloff and turnover switches also make a big improvement if no one has changed them...if you are using vinyl (most folks with a Citation I have it for vinyl I assume).
Yes, they are a very good preamp when rebuilt.
cheers,
Don
