Ok, who’s the yahoo that performed a WO PL400 SII quasi comp update (control board, outputs, and caps) and glued the caps to the bracket?? Had to destroy the caps on removal and will be a pain to clean the bracket before placing new updated caps. Although I’ll admit, the update was one of the...

Finally found the source of a very annoying buzz at very specific frequencies in my bench speakers. It all started with testing Model ONE amps on my bench and was unsure of the source, was it the speaker or upstream electronics… It only occurred on the left speaker. I decided to tear into the...

Model ONE build of S/N 005 & 006 has commenced. Looking forward to completing a 100% White Oak designed amp. It's obvious from inspecting the PCB designs and Chassis layout that significant thought went into this design and project from Joe. Acquiring all the components for two 1000W amps...

Finally finished my 700B after putting it on hold almost a year while building amps for others. It's a complete White Oak rebuild with new chassis and heat sinks, including WOPL 1000 insert between the meters. I decided to go with a slightly different look from the Black with Blue LED lighting...

Based on recent experience with streaming music services, I have decided to jump all in on digital music sources. I realize this forum is dominated by analog interests (LP, Tape, Vintage Equipment…), but I thought I would share my experience in the conversion to digital and maybe help teach...

After finishing a PL400 S1, I plan to start building a PL400 S2. The sickness has begun, I could not resist. Just received an email that all the White Oak components have shipped, so tear down begins. This Series 2 was used hard and put away wet its complete life... It's very rough around...

Looking for input on my next preamp project to pair with a full WOPL PL400. Specifically, looking for a quality 2 channel setup to drive B&W 802s using a S2 PL400 or 700B if I can find one. Started looking at the C-1 or 4000t, but the more I’m looking at the 4000t I have no use for all the...
