I removed some caps to test. Some are good, some are at 20% and some over 20% out of spec. I decided to recap it. Teac used Chemi Con caps. The electrolytics are mostly SL's, or general purpose, several LR's or low ESR and four CEKU which are really special. They measure spot on. There are some Tantalum and dipped Tantalum. I removed a couple, and they are well within value spec.



I found a source for Panasonic FC caps that will cover all values needed (with exception of a Muse bipolar). So, the general-purpose caps get an upgrade.



I was concerned about fakes, but they look real good and test well for value. (Sencore LC-53 Z meter used to test). Several were tested for leakage, and they passed. I test and write values down on tape or separate them in bags and plastic storage boxes. These are 10uf, (I didn't write decimal, 9.8, 9.9uf). It allows me to closely match R and L channels and I can trust the marked value when I install it. I test and record the removed caps as well.






First blood, PS done. There are way too many wires to desolder to get the boards completely out. One can cut zip ties, get some slack in wiring and move boards for best access possible. I take pics or notes to make sure polarity is correct. (The markings on the board may not be visible). I powered up and tested PS before continuing. All is well. No smoke or sparks.



The lower boards may be slightly easier.
