[R-390] The Nolan Lee Memorial 390A Capacitor List

[Drew Papanek]

Hello All,

Nolan Lee's R-390A capacitor list is all-comprehensive, perhaps too 
comprehensive for those of us who wish only to replace those pesky 
failure-prone paper and electrolytic caps.  Shortly after Nolan compiled his 
list , Wei-i Li released a list comprising just the paper and electrolytics.

Much more information on capacitor replacement can be found in his "Pearls 
of Wisdom", a distillation of postings gleaned from this forum over the 
years.   Goto r-390a.net    .   Click on references, pearls of wisdom and be 
amazed. Be very amazed.

So without further ado I present for your edification We-i's posting:

Drew

I had a chance to go over Nolan's R-390A cap list, and rehacked it to
reflect my needs. This is only a working list, so let me know of errors. A
shopping list for any recap kit would include:
- --------------------
(13) 0.1 ufd
C256, C309,  C504, C505, C517, C521, C528, C531, C536, C538, C543, C547,
C548,

(7)  0.033 ufd
C275, C529, C533, C534, C541, C545, C602

(7)  0.01 ufd
C549, C553, C601, C604, C605, C607, C608

(I'd go with the SBE 716P 600v OD's at the outset, seeing as how recapping
is not a trivial project)

(3) 30 ufd 300 v electrolytic C603
(2) 47 ufd 300 v electrolytic C606

(Sticking new electrolytics in an empty octal relay case as Tom Norris
did, worked out swell for me)

Finally, only one needed of:

0.047 ufd 100v C227
8 ufd 30v tantalum electrolytic C609
50 ufd 50 v electrolytic C103
2 ufd 500v C551 oil-filled paper
0.22 ufd 100v C101
- --------------------------
Obviously C553 and C549, and the AF deck electrolytics C603 and C606 take
precedence in any recap project, as stressed in earlier posts. Now here is
a chance for AES to make up a 37 item kit (just kidding)......

Thanks, W. Li
