I'm waiting on some new inductors and 2.2uF MKTs.

Gmorris, I swapped out all the 10uF caps for 2.2uf electros and it made no difference to the start up pop.

Refer to the TA2020 specification, I just find the leg 10 and 13 of TA2020 is high pass filter should using 2.2uF MKTS instead of electrolysis cap (shown in your photo). Please evaluate it.

Thanks for posting photos of your work, Col.

What about that row of capacitors between the heatsink and the speaker jacks labeled "100"? Are they capacitors? The ones on your new amp are different from the ones on mine. If they are caps, they look like they have a cover on them.

Thats the Output inductors. My other Lepai had black ones that were a bit bigger than these blue ones. I'm going to replace them when my others arrive.

Col,


I seen your photo, the left hand side big cap is much bit than mine one. Can you tell the capacitor value.

I don't have the 2 big yellow cap, is it changed by yourself?



Thank you.

The left hand "big" cap is the power stiffener. I replaced the original as it was only rated at 16v and was of dubious quality, I used a panasonic 2200uF, which is what it said on the PCB, I also had some handy

The big yellow 2.2uF are 250v polypropylene film. I used these to replace the 10uF electros. These are the input caps.
