[Heathkit:Yahoo] SB-401 Info/Experience needed.

[John P.]

Tom,
   
    For what it is worth.......
   
    I have an SB-101 and there is a 20uf-35V cap near the AF output amp tube that did fail and had to be replaced.  Jus for sanity sake I did replace the other on on the board with the mic amp and RF amp.

          Hello, all. I'm working on adding the SB-401 to our line of 
electrolytic re-cap kits, but have come up with a few questions for 
those of you who've owned one of these.

On the "Carrier Generator Circuit Board" there are four small axial-lead 
electrolytic caps: 10 uf @ 15V, plus a PC mount 20 uf @ 350V.

1. Have you ever experienced a failure of any of these?
2. If you were doing a rebuild or recap of an SB-401, would you replace 
these five capacitors as a matter of course?

In the power supply, there are the two 125 ufd can-type capacitors.

3. If you've replaced these caps, what kind of caps did you replace them 
with?
4. Did it take any modification(s) in order to facilitate whatever it 
was that you used?

5. Is there any other words of wisdom regarding recapping the 
SB-301/401 twins?

I'm putting the finishing touches on the SB-301 recap kit, and would 
really like to be able to supply a good practical kit for the '401 as well.

Thanks for your help,
Tom
