16 hours and 400 transistors later (with more to go), I've come to a few conclusions comparing the TC1 and the RG Keen method side by side.... -The TC1 is a snapshot of measurements, which means it will NOT catch an instable or excessively leaky germanium transistor. You need to see this over...

That's definitely good news to hear. Curious.... similar readings for hFE or Iceo and leakage (or both)? I was testing a few hundred transistors last week and the readings were not the same. In the ballpark, but definitely not the accuracy we wanted. That said, it was a terrible batch, almost...

We're big fans of the TC1! We have them all around the Cusack campus, great little tester for all sorts of things and super simple to use. As discussed, it is not the perfect tester for germanium transistors. It will get you in the hFE ballpark (reporting higher from leakage). We'll sometimes...

Swap that A500k gain pot with A1Meg. You'll still be able to get all the low gain tones but roughly twice the gain at the other end of the sweep.

Hey! 16mm pots at the moment are still a mix of a few brands. Alphas, Mammoth, and our Cusack pots which we will be switching to entirely once we deplete the rest of the other stock (ran out of Vimex recently). Alphas and Mammoths are virtually the same except the Mammoth ones don't have that...

Oof, that's an expensive pile up. Are you cleaning the area around the chip with IPA before and after installing it? You've probably already thought and done that (many times hah) but worth mentioning in case. Hope you end up finding it's something simple but from the sounds of it you've been...

These are old stock stuff from Mammoth. Have tons of them. Bunches of the premade cables, too. Unfortunately after rummaging through tons of boxes there is none of the proper cable to go with them. Bummer. If anyone finds good compatible cable let me know, I'll list it in the product...

Thank you for the kind words, @manfesto ! These teeth jacks are my very favorite jacks around. Would anyone have interest in these in any other configurations? Such as TS or TRS switched? We thought about a TS (2 lug) but the cost difference is negligible so we stuck with TRS (I usually snip...

That doesn't seem right. DM'd, I'll get you taken care of.

Added extra coupon. Kit is free with $25 of other parts, don't tell my boss :) If you've already ordered one I've zapped the $$ back.

*EDIT* These coupons are old and have been voided, thanks to all who grabbed the kits!* Howdy! First post, love seeing everyone's builds and other things you're working on! For those interested, we've assembled a parts kit for the Auditorium. Includes all on-board components plus some rubber...
