. . . move the Clean channel caps from the board to the pots to prevent oscillations. Funny that the lower gain channel had that problem. Lead dress matters. The "Trainwreck" channel in these is more heavily attenuated than in Ken's. I think Gerald didn't like the gain. I'll take a look at what val...

Firestorm; I know what you mean about unfinished projects. My laboratory is FULL of them. Whichever way I turn, there is more to do. Structo; Interesting if that is the schemo that you got with your Climax?!?! Notice when you open it, the thing says "New JoyZee Amp Kit" ?!?! From reading an old Goog...

The 12AU7, 12AY7, 12AT7, 5751, 7025, 12AX7 also noted as ECC83, and many more can be swapped in and out as you like. Thanks about my dog, something is going on today as my other dog is chasing ghosts around the house not sure what he is seeing. :lol: Dogs (and other animals) are WAY more sensitive ...

Small value resistors tend to get written as "1D5" with the "D" meaning decimal (as in 1.5R). So following the same style, 1K5 is 1500R and 1M5 is 1,500,000R. Confusing, I know. But the one that still stops me is the capacitor shorthand, like "10mmf" for 10 micro-micro farads... I'm guessing that t...

Hey John; Thanks for the info. I'm just getting back into playing with vacuum tube electronics after a rather long hiatus. (30 or 40 years?) Here's how long it has been. I'm glad that you wrote "1k5 (1500k) screen grid resistors" because I was wondering what that 1k5 meant. We would have always writ...

Hi Mark; Oh, man, just noticed your hound dog and the date~! Sorry to hear. My own Chocolate Lab is nearing 13 (on Halloween) and I can feel his time coming. His back legs and hearing are shot, but his spirit is still full and loving as ever. What a blessing those guys are. Thanks for the 12AX7 / 12...

Hey TerFore (& Mark); That is one NICE looking amp! Good job. That is very similar to what I am wanting to do, as my amp came to me already built (not sure of the year, but am guessing 2006-2008 or so) and in a 2 X 12 tallish cabinet with the speakers one up and one down, barely the width of the amp...

Mark; THANKS so much for the Kit Instructions. I have a few of the pages (from the previous owner / builder), but not all. I do have the Parts list and Layout, which I will scan and post here as well (as soon as I can figure out how). I just DLed the Trainwreck Climax schematic (posted on the older ...

Rather than revive this old thread, I'd like to start a new one for anyone owning and interested in this amp (going forward). Just got one and want to bring it up to it's full potential as it looks to have promise. New Post is here; Kendrick New JoyZee Trainwreck Climax (KendWreck?) Amp Kit ? https:...

Kendrick New JoyZee Trainwreck Climax (KendWreck?) Amp Kit ? Just arrived here from reading the other (older) post regarding this amp and kit and was wondering about other owners experience, tweaks and mods. (Would love to hear and see more from Gerald, too.) Quick background about me. I began life ...
