Power transistor help

Sending shit out for stripping and re-anodizing is expensive and a waste of time. You can buy new ones and if you are using a new face plate.... Your set. If you are using old face plate and it's not perfect, and your handles are not either, who cares. Some guys like the patina and I have sold many amps in original condition.

Skip all the work. You can order any size and material/style ferrules you need here. I even have my handles custom made here and the price is right. plus, you don't have the look of drawer pulls and closet door handles some have used. I have bags of these things.


Take your time and peruse this link. I have been doing business here for years. Have calipers, will travel.........

Lee, I've outfitted many of amps with these. I did have issues with finding the correct spacing for 700B/Clair Brothers since they used the same spacing. But they are really nice. Painted, or anodized, chrome, polished, satin or raw is the order of the day. That was the reason we had 700B handles CNC'd for us, I didn't find suitable handles with the spacing and style.

Joe,

I already boxed up my backplane boards for shipment to your shop. In my excitement, I did not identifie myself inside of the box. Hopefully you were not expecting backplane boards from a bunch of people this week. Feel free to use my boards as a before and after on this forum, so others can learn from my mistakes. Also, I had installed the first roll of transistors, are the sil pads reusable?

Hi Gary
Did you ever ship these? I have been looking out for them to arrive every day...

Joe
 
Your shipment

Joe,
I've shipped these 12/13/22. Guess they got slowed up in the Christmas rush. Everyone have a good and safe Christmas!!!!!
 
Merry Christmas Gary and Happy New Year
I worked on your backplanes today, a before and after picture.

All the PEMnuts pulled down fine, removed a ton of excess solder with Soder-Wick. Word of advice to backplane builders on amount of solder around the PEMnuts, use it sparingly. You should see the vertical sidewall of the PEMs after the solder process is complete with a nicely radiused meniscus around the base of each nut where it adheres to the pad. It is not "the bigger the blob, the better the job" that applies here.

Each PEM had the excess solder removed from the top of each PEMnut so you will have a clean interface with the nylon washers.

I also will be replacing some of the 22AWG interconnect wires as the insulation is nicked. A word to builders, do not use automatic strippers on Teflon wire or this nicking will result. Use sharp Ideal Industries T-strippers for Teflon wire.

I will be wrapping these up, cleaning well and shipping them back to you.

Joe,
I did not think of you working through Christmas on my boards, of which I thank you!!! I’m glad you were also able to use these boards as a teaching lesson for others. After I get this 400 fired up, I have another one waiting to be upgraded. This is so relaxing to me in my evenings. Again many thanks, and everyone “Happy New Year!”
 
Hi Gary

All PEMnuts fixed, excess solder removed.
All nicked wires replaced, solder touched up.
All excess solder removed from component joints
All lead lengths trimmed short.
All PEMnut threads chased.
Cleaned, cleaned, cleaned...

Will box up and get on their way back to you.
Joe
