Here is a rear shot.
The inside is not quite as tidy as the builds often seen here.
This amp is wired true point to point.

I remember the 2 builds you posted years ago they were sharp amps.

Partial gut shot

Not 100% complete at the time of this photo but close enough. Not a full chassis view but most of the components are visible sans panel controls and switches. Vacant 9 pin socket for future mods etc.

Both videos are good I remember that older video too.

I kept the photos of the two amps you built great looking amps. I see on your old post the photos are gone.

Thanks. Yes, the photos are gone thanks to Comcast retiring its ftp feature for all clients including me without notice.

I was prompted to revise the old video noodling down to just a couple of riffs for an interested player who requested just a little taste of the Quad 36 tone.

Very nice. I am curious how your boost work, is it like the boost on a dumble build were the tone stack is bypassed?
Just working on a trainwreck build myself (Liverpool) .

Cheers

Keep the iron hot!

Not related to the Dumble tone stack bypass, just a simple cap switched in or out on the cathode of the tube driving the tone stack.

Thanks. Point to point is rarely tidy looking.
The yet to be installed switching wire harness assy and subsequent wire dressing end up looking a little less messy once installed.

I think it's tidy looking under the hood.
PTP is a lost art form.
Congratulations. Great looking and sounding build!
