So recently I got myself a Victor M-L10 poweramp, pairing it up with the naim nac62 + hicap. I run off the signal cable from the pre itself to the poweramp as it is a shorter signal length. Now the issue is that im having a buzz on the right channel, I just tried making a chassis ground to the...

sorry for a very late reply, Do you still have the transformer?

I did an inductor change and the input capacitor 4.7uF change, and holy. The bass had more detail but the problem now it sounded brighter. Is the 5 watt resistor will work fine, just changing the L pad.

I’m planning to recap my crossover, does changing most of the caps to film/polyprop still enables me to put it back to its small case? I also see that the red non electrolytic looking cap looks small enough to fit right back in.

Yea... but that will change next month. I’m swapping all back to tants. Did not know that the techs will swap it to lytics last year.

Like this?

Thank you, so it is the most left and the most right. Front of the most left and the rear of the most right.

I saw a lot of method, and that too, just measure across one emitter resistor instead of two, then determine if it needs more or less. But seing that you can also do the one on the right is also interesting. But what if I want to measure across two resistors? I’m guessing hook up to the one that...

@misterc6 i saw one of your replies from a post back in 2011. I was not able to open the picture, so could you provide the picture again? Thank you

I also Saw patevil's picture which is

oh,okay. Any tips to how to check the bias on my unit, I checked and it the boards is NAPA6/3

And also, there is no input and speakers connected.

So I wanted to measure the bias of my amp, I pronged the circuit as shown in the pic. Please help, it is serviced by a tech and in a month I want to bring it back to tantalums.

I removed it to check all the transistor cuz the technician said the transformer is fried, but no way it is dead. So I looked more into the amp and checked the primary and secondary winding, it measured fine. Anyways, it is the feedbacks which is intermittent failure'd. Swapped it out and put...

This is the insulating washer that came with the amp
