Power Designs TP330 Power Supply

I decid­ed to take a gam­ble on pur­chas­ing a Power Designs Inc. TP330 triple out­put pow­er sup­ply. It was a bit rough look­ing with a bunch of stick­ers on the front pan­el, but no scrape marks from past stick­er removal vis­i­ble. The sell­er stat­ed that the bot­tom ana­log meter was non-func­tion­al, but the out­put ter­mi­nals mea­sured volt­age that changed with the volt­age knob.

Repair and cleanup of a Power Designs Inc. 5015D pow­er sup­ply that I pur­chased on Ebay.
This was one of the bet­ter look­ing 5015D pow­er sup­plies that I have seen on Ebay, that was not over­priced or includ­ed an over­priced ship­ping charge. The list­ings con­di­tion descrip­tion said ” ful­ly oper­a­tional and func­tions as intended”.
