I'm shocked that the admins on this site allow this type of behavior. I would expect this kind of thing on a site with a teenage demographic but not on a site composed of accomplished adults. You lack tact and class. Your sophomoric, adolescent, and unprovoked criticisms do nothing to advance...

Here are the pictures that have been requested. Sorry I didn't post them sooner, I had different expectations when I first posted.

They will get coated with a true ceramic by SwainTech. If that's not enough, I'll wrap them as well.

Joe, I had a different vision in mind when I came here seeking assistance. I assumed the (mostly) wonderful group here would walk me through some test procedures using instrumentation and measurements. I hoped this process would further my understanding of the circuit operation and electronics...

Oh yeah, that makes sense. Why pick one frequency when I can have them all. I was taking the scope for a test drive along with the amp a couple weeks ago. I had 8Ω resistors across the outputs along with the scope. At a very specific point the sine wave "grew spikes". I thought it was...

Thank you for jumping in!! I most certainly installed everything you provided. I'll be sure to post this information in the future. I appreciate the clarification on the bias test points. I assumed this to be the case but I've been burned by assumptions too many times to count. I'm testing...

I asked for help in learning how to troubleshoot a problem. I'm not interested in being spoonfed the answers. You and I are not the same.

I'll absolutely do this as a next step. I just picked up a signal generator a few days ago. I'm curious, is there a frequency that's preferred over another? I can't imagine there would be unless an issue were occuring at a specific frequency. But I don't know what I don't know so I have to ask.

Damn Sniff, did someone $hit in your raisin bran this morning. The ability to solder and the need to test a transistor are not mutually exclusive. Hell, they're barely related. As I mentioned in my post, electronics as a hobby have always take a back seat to other interests. See below for an...

I didn't have the attenuator wired correct initially but i discovered and corrected that issue a few weeks ago. I wanted to replace them but couldn't find something I liked with the same resistance. I cleaned them thoroughly with Deoxit. For trouble shooting purposes, I've removed them from...

Both channels are affected as mentioned in my post. The distortion appears in the right channel before it appears in the left. Weird.

This is the kind of direction I'm after. I'm working another 12+ hour day. I'll put the peddle to the metal and see what happens to the rail voltage. Is there an acceptable amount of voltage drop? Thank you for your input!

Thank you for taking the time to respond. Electronics have been an On/Off hobby since I was very young. It was my father's favorite past time so I had access to a modest electronics workshop throughout my childhood. Fwiw, soldering was always my favorite thing to do. I don't even remember...

I just finished a WO build on a 400. The left channel sounds great. The right channel is quieter by 25% and also clips or distorts in some way at approximately 50% volume. I don't where to look. Any help, advice, or suggestions would be very welcome.

By George, I never thought of that!! *gobsmacked* I've perused the instructions a time or two at this point. It's been a few weeks since I checked the bias. I'd like to think I followed the instructions properly at the time. I'll have to check my notes.

RCA jacks are new and installed just like the originals. I'll double check every then connect my source directly to the PL14_20.

Oh! That's helpful. I should have looked at the schematic rather than the written instructions. I'll double check bias this evening. Should the bias be the same (or very close) between B+bias to Output and B-bias to Output? Clearance is a good thought. Space is a little tight so I have been...

I'm rebuilding my 400 s2 using the full suite from White Oak. After nearly a year of intermittent tinkering and some intense trouble shooting over the last few weeks, I was finally rewarded with the clarity and precision I've read so much about.....almost. The left channel plays normally. The...
