I have 4 original knobs that could be part of a trade for a dual primary transformer! Plus WO matched quasi-comp transistors, original driver board, WO quasi rev D driver board, WA DC protect board, original incandescent light board, original back plane, and more...

Great, thanks Lee. Now for the real question...you got one in your stash you'd sell. I have a bunch of PL parts I'd offer up as a partial trade...

I'm interested in buying a PL 700 Series 2 dual primary transformer. Does anyone have a spare in good shape they'd be willing to sell? Also, I assume the dual primary will mount to a 700B chassis without an issue. Can someone confirm this assumption? Thank you! -Steve

One of the cool features of the switch driver board is that it has a built in shut off circuit for thermal protect switches using DC. This means I don't have to run one leg of AC across the driver board and down to the switch locations. My wires now run directly from the switch over to the power...

Thanks for the feedback guys. I'm not a good authority for feedback regarding Rev D and Rev E. I changed too many other bits for a true A/B comparison (not to mention 6 weeks of listening to a different amp). Furthermore, I can't claim to have golden ears. To me, the amp sounds noticeably...

So after it was built, tested and sounding good, I dismantled and cleaned up the faceplate. I was the guy running his mouth about chrome plating the faceplate and having the original artwork re-silkscreened. However, after seeing some Burmester equipment at a Chicago audio show that was chromed...

I upgraded the interconnect hardware with some nice but not crazy hardware. I wanted to use copper in the signal path. I used DH Labs RCAs which worked well with an insulating, reducing shoulder washer from a well stocked hardware store. The Cardas binding posts are Rhodium plated copper and...

So I clearly brain-farted and ran the thermal cut out switch wires across the backplanes. That has been corrected (more on that later).

About a year ago, I built a Rev D driver board and put new transistors into a quasi-comp 700B. Joe, Lee and the community were really great helping out an enthusiastic noob. I enjoyed running the amp for a year but had been planning on going the next step. Finally, audio building season arrived...

Fred - the aluminum knobs you used look great. Can you please provide the source? I'm looking to chrome the faceplate of my 700B and the knobs.

Lee, are those the group buy caps or your personal stash?

Ah ha, I get it - "the right place at the right time store". Damn, those are hard to find.

Joe, can you provide the part number and a source for the mil-spec teflon shielded cable you use?

Yeah, I answered my own question when I got caught up on Lee's thread. Very exciting preliminary results!

Hi Joe. Any updates or is it all wrapped up? If I see correctly, the last pictures don't have the output transistors installed.

Yes, transistor pins not transformer pins. I've had a long day too...not nearly as long as yours though Lee. Just very interested in your progress. I totally understand how the real world can impede doing great things.

Also, the kit looks awesome and great work by the both of you. Do the transformer pins get soldered in or will there be PC board pin sockets?

Hey guys...are you stuck? Not many updates the last few days. We are waiting with bated breath...

Indeed, it is about 5x the power I'm used to so I'm certain to go through some conditioning. Thanks for the document, Joe.

When you guys run your 700B, do you keep the L/R volume pots at 100% and use your pre-amp for volume control? I'm not sure I trust my meters. With my meter switch on 0db, I drive my speakers to pretty anti-social levels and the meters stay in the lower 1/3 of the range. I'm driving JM Labs...
