I understand the rules and want to enter the contest.

The last post in this thread is from 2009. You'll do better to start a thread of your own and post your question.

Progress report. HV board is done, everything replaced. Electrolytic caps replaced on the other board.

Thank you. I don't know how to do it, but at least I'm aware I should damn sure figure it out.

The burnt looking resistor.. is that a red band or orange band? I'm pretty sure I've circled the correct resistor on the schematic..the green wire pictured goes to the potentiometer marked "power". looks more like 15k to me than 1.5k. I wish I could read the damn numbers. d

I removed these and they have indeed drifted (upward). I am not able to read all of the values on the schematic, so i'm just going by the actual part I see. Some of the values I can read on the schematic don't match what I find in the box. Do I follow what it says or what I see? For example...

First picture is before i did anything. Dust bunnies and mystery brown schmoo. I managed to get both boards free enough to work on them. Waiting on more parts. Any reason to check any of the other parts on the HV board while I have it out of there?

i heard they're crappy

Thanks, I will start there. I have some parts on the way.

Thank you for taking the time, Brandon. Incredibly helpful. I think I understood a little more than I gave myself credit for, and some of it I had just plain wrong. The amplifier was working with nice clear sounding audio reports on SSB. I took it upon myself to clean it, and now get reports...

I want to understand what is going on in this circuit. I can identify some of the components, but want to understand the design of the amplifier circuit. I may be a lost cause but even if you can point me in the direction of a book to read, or video series to watch, that would be helpful. I...

I understand the rules, and wish to enter.

It was an impulse buy I guess. I have a DX10 I enjoy and didn't "need" the 7100. Minty one for about 700 bucks seemed a decent deal.

I just bought a 7100 today. I like the way it looks!
