I solder the backs off the PEC pots, but the guy that showed me how, made me promise not to tell how.

But if you want I'll sell you a presoldered PEC pot assembly (with 18guage buss) with the .1 Mustard for $20 more than parts, plus shipping.

Or you can buy the parts, send them to me, and just pay me 20 for doing it. Plus shipping.

Mike that doesnt seem right - please tell us the big secret. i just solder the lugs - no need to solder the housing. but come on - that is no secret to keep if it is some magical solution.

plus u want to charge 20 bucks - give us a break over here!

The back is only held on by the four tabs bent over the shaft side, on the edge. It's no big deal to pry a couple of these up and remove the back. I've had to get into them at work before, it's no biggie.......

You've just got to ensure that your spacing is correct when you solder!!!

There are no secrets on this forum

Give it up!

I already gave it up for him..........

It's really pretty straightforward........

Ok Flames I get it, take the back off, solder on the buss then put the pot back together, right?

I promised not to tell and keep my word.
But people ask me how to do it, so I thought I might offer a way for them to get one. I like the way it looks, but it's not for everyone.
I didn't think $20 was that much for the labor, to build it, treat it, and package it.

Sorry

Show us a picture of what it looks like please.

Here's a pic, and I have never taken the backs off.

Ignore the way the .1 is, That was an experiment,

I run it to the middle tab, and run the end tab to ground like normal., but I can also build them with 4.7k/.68uf 73 style with the 25k.

Yup........

I take it this is to prevent overheating the elements inside the pot? How high do you guys have to crank your irons to solder to stainless steel? I'm using PECs in my current built but ended up just soldering a bussbar to the bottom of my turretboard on the pot side. Quite a cramped way to work.

is it a cosmetic thing? why the need to solder the backs of the pots? only 4 of them need it and the lug on them works fine.

With my technique, I have never hurt a pot soldering the back.
I have a real nice Hakko soldering Iron, and it doesn't take long on 850, after I've prepped it right. That's the key.

Yeah it's cosemetic in that it looks like something out of a WW2 miltary equipment. To me it's stout looking with the 18guage, and I like it.
But the Pots George has, look even more accurate to the orginals, and are easier to solder to the backs, if accuracy to the originals is your goal.
And it will sound the same running it through the terminals or soldering the back.,

I've done all my amps like this except my first 1st, and a restore, and I have never had a pot fail, and my earlier ones I wasn't as good at it, and
applied heat longer.

Now I'm really quick.

4 to 5 seconds tops.
I don't try to cover the whole back, like used to.

I think a lot of it is personal preference, Mark. Some solder to the pot backs, others run it through the pot lugs (as you already know), and others solder it to the bottom of the turretboard like this.

Mike, im not much into looks myself - more about performance for me. but i can understand it for people who are.
i wonder if the have the pots drifted any with all this heat on them?

oo i like that look! but where and how are the pots grounded? btw what circuit is this?

...the phase inverter circuit is intriguing.
