I have totally modded the heck out of my Teac A-L700P. It uses a Jensen 10,000uf 40v for the main power supply cap and Jensen oil 2.2uf cooper coupling capacitors. Inductors were upgraded. The input resistors were changed from smd resistors to riken-ohm resistors. The output filter supply was hard wired with new caps and mills resistors to tripath specs with the speaker relays bypassed. I wish I could take pictures to show you how everything is hook up. Here is a diagram I used for turning the amp into battery power.

You do not have to worry about powering the relays since you are bypassing them, but you need to power the protect-on, speaker-on, etc. My millimeter reads them at 3.5v, but I think you can get by with 5v. There is a 5v regulator on the main board which I power with one of the 12v batteries. When the amp is powered on, the batteries connect in series to produce 24v and parallel when charging.

I know i´m a perfect alien in this forum, and in electronics in general..., but i would really appreciate if someone could shed some light on the TEAC capacitors upgradability for me. There is one 35V 1000uF (power decoupling?) next to the inductors that could/should be replaced by a 50V one but how reasonable woul be an increase in capacitance, 50%? 150%?
Then there are the two 2200uF 50V on the power supply board, are these power supply filtering/smoothing caps? What about that really big (i believe it,s a 400V 220uF) near the transformer, is this the one Tripathdude replaced with the Jensen?
Help, i´m lost here! I just want to improve slightly the stock unit by replacing some parts and have some fun in the process.
Thank you.
