Can’t believe the resistance on this one. This site is all about find new and improved but not for this part. I still going to try them

No- that’s not what I meant. Experimentation is what led to what we have now, but be cautious with what you’re doing, don’t be haphazard with something that’s far from the norm. Try it, monitor it closely, and post your results.

100K Volume pots (Round Shaft)

652-PDB241GTR02104A2 (The Guitar option)

652-PDA241HRT02104A2 (The High Torque option)

652-PDA241SRT02104A2 (The Standard Torque option)

All are Bourns Carbon, 1/4W, 100K Ohms, Audio Taper, 1/4" Smooth Shaft Diameter, and 3/4" Shaft Length.

I like the second one.

Coolness.

Prices of the Thermal Switches are now $13

I ordered some for my stock.

Are they the same for 400/700?

Anybody have a source for the 700II level pots? I've got two loaded with nicotine.

Back around post 110 bias transistors came up. I've been using MJF31's which is a TO220 package with isolated tab. The leads are much stronger than the TO92's. What is really nice is the connector from a 3 wire power cord on a 12 volt computer fan motor has the same spacing as the transistors. the fit is tight and no solder the leads.

P-straps for bias Transistor and w wrong transistor, I removed it and for that price, it's well worth it to make a lot spares. "20 TO-92 HI GRAIN SILICON TRANSISTORS W/HEAT SINKS CLIPS 2N3402" who knows how many he has.

F... those P-traps (sic). They belong in a sewer. The common failure mode is a broken lead due to the mounting stress. The result is all of the outputs turn full on and go to war with each other. 12 blown drivers/outputs per channel on 700's.

Sorry for posting. So what do you use? you still need them?

 

[WOPL Sniffer]

never had a failure of the Bias Transistors due to anything.

 

[Gepetto]

When you install the WO backplanes, lead breakage of the bias transistor becomes a thing of the past.

Perry is right, the bias transistor application is a very, very low stress application, the mechanical stress on the original PL mounting method with flying wires was the only stress the bias transistors saw.

 

[Skratch]

My bias transistors were heat stressed quite often

Do you need P-straps?
lol All the wire could Break. Ever time I moved the Org PL Board I always had to look for broken wires.
One time I put the control back in and it worked. The control board had a broken wire and it touched the solder pad and worked. than later I took the board off and the wire flipped away from the board I just LOL (typical)

New flexible wire should be install, I use silicon and this will help prevent this from happing. I hope

 

[WOPL Sniffer]

What do you use "Silicon" for?????? Why on earth would you put silicon on the board???


HUH????

I think he means silicone-rubber insulated wire. It's really soft, like inflatable bouncy betty.
