Title: Power supply advice please...
Post by: rtate on February 03, 2009, 07:38:36 PM
I have a vintage van alstine amp that had the front end powered from an aux board that supplied +/- 15Vdc. While trouble shooting a hiss problem I inadvertently damaged one of the dual voltage tracking regulators(SG4194CJ)
It appears that these parts are not available unless i want to pay a $200USD minimum fee to parts brokers....
So my alternative is to build my own P.S.

Do you have any suggestions on what i should use??

You can probably use 7815 + 7915 or LM317+LM337

heaveno PA , sorry for the confusion.
What i need is a completed kit for a +/- 15v supply.
The damaged part is a 14 pin dual tracking reg chip, so I can't just sub in a 7xxx series part.This is 1978 technology and i was looking to upgrade.

Mentioned regulators are pretty easy to patch in if it's only to get it fixed but if you want some replacement maybe my JSR03 (positive) and JSR05 (negative) will work. It depends how much space you have.

So you don't think something like the QSXPS kit would be suitable??

It will indeed suit if you'll have the space for it.
