Where'd you get the chassis? Looks great.

Thats the ebay "soundtastik" St-70 + updated chassis. I thought that the cleaner looking chassis, and deleted multicap would give the Dyna a newer, classy look!

Nice job. That chassis definitely is cleaner looking. The big bottles look great too. I have one running EH KT-88s in triode and it doesn't look as good as yours. I also like the locking bias pots. I have used them myself.
A question...where are the bias check points?..on the rear panel?

Well.......... here's a dirty little secret. There are no external bias check points! I went the dangerous route, and used locking hooks on the probes of my DVM, and hooked them onto each side of the bias resistors. It was quite interesting being that this was the first time I had ever biased a tube amp!!!!!

The amp looks great, very clean.
Those Octal sockets look excellent. Where did you get them?
Thanks in advance.
