Thel in Germany carries the TKDs... http://www.thel-audioworld.de/bauteile/regler/Potis.htm Otherwise, Japan pretty much.

Happy Birthday Colin!

Happy Birthday Steve!

Hey Ryan, I'd definitely be interested in going. Chris

Yeah, Shar tools look nice. They’re only 10 miles from me and we go up to St. Charles fairly frequently. Sent from my iPhone using Tapatalk

Kevin retired from Northwestern a year or so ago, so none of those links are active anymore.

Happy Birthday Jeff!

Some interesting reading (didn't read all of it though). Bruno Putzeys knows his shit. MQA seems to be a farce.

Nice! BTW< your workbench is FAR too clean (note to Pars... clean your shop).

My full size SS Dynalo (thru hole MPSW parts) runs fairly warm at 17-19mA bias, but nothing like mini warm. I haven't cased it yet (this winter), so I'll see what it is like when cased. Here is the link to the spreadsheet I created for tracking what users are using for bias and what kind of heat they are seeing: https://docs.google.com/spreadsheets/d/1D5LDuRdupZRoWR-GfAd03fkFSBAMY4-E_VcYfCAI1Z0/edit?usp=sharing I don't know if HC allows sigs or not, as I thought if they did I would put the link there so it didn't keep getting buried.

I would measure the bias on every 20R resistor and go from there. Note I did say every, and I wasn’t joking. I have had bad solder joints which effectively took a transistor out of the mix; these looked good to the eye, so you need to make sure they are all working correctly. Normally on a full size Dynalo I like ~17mA bias. On the mini, because of the thermal considerations, 15mA is the highest I would go. 13-14mA would be a good target. Sub 10mA is very audible, and too low in my opinion. Sent from my iPhone using Tapatalk

Yeesh! Hope it doesn't go any lower Jeff. For your neighbor's sake 🤣

RIP Jessica. Sorry for your loss Dusty.

They have both the replacements in stock -200,000 of each or more. Sent from my iPhone using Tapatalk
