3 WOPL's in the pipeline (+1)

[WOPL Sniffer]

Add a set of White Oak Audio Design Display Boards, and rework the switch plate with new switches, it's ready for another 40 years.

I'lll get this all wired together and move on while waiting for a Black Series II face plate to get here.

Did you clean up the attenuator potentiometers or are they new, they look great!

They get disassembled, inspected and cleaned/re-lubed if they pass inspection

For the re-lube do you use a heavy grease to give that damped feel? What lube do you use?
I think these were CTS pots and the older ones were made better than the ones made today. So I agree it is worth the time to inspect, clean, and re-lube them. I have a box full of them. Maybe I should check them out.

Fader grease

I have also had excellent luck with these

I put a set in Brent's amp in January and he uses it every day with no issues.

I have a couple of small tubes I filled from a 5 gallon pail of "Extreme Pressure Grease" Mil-G-83261, we called it 'Jet Black' in the Navy. Sniff probably remembers it. If I open a tube here in FL, some of it will eventually get on the wall of the house in Sterling, MA.

Thanks for the photo.
I have used those pots, Mouser P/N 652-PDA241HRT02104A2 except with the last two digits being "B0" instead of "A2" for a Linear Taper pot. instead of an Audio Taper pot. I have never found a parts list for the PL700B, but the PL400 II and PL700 II parts lists show a 100K Linear Taper pot.

700B Series II QWAZY WOPL rocking out. added some volume pots, and reworked the LED's to get the filters lit. Just need to do some adjustments.

Sniff, have you ever had to replace the little plastic Power and Display pushbutton covers? Is there a source for those? I ask because the Clair Bros Audio amps have very corroded and pitted surfaces on the pushbutton covers.

Sand and paint them. Never found a source besides dead units that went to the dumpster after being robbed.

Buffalo Bob used the same buttons on about 100 different units between PL and Carver. Find a cheap junker and Strip it.

 

[WOPL Sniffer]

I've scored a pile of buttons, handles, knobs and other goodies for cheap. Some units were sent to me for free of for labor trade.
