Dynaco ST-70

Dynaco ST-70 #2 upgraded
- using Solen caps on a new 7199 board - sounds "bright" but "defined" bass, mids and highs on a pair JBL G300's. I am going to try some Auricaps I have in stock to see the difference. Hoping for a more mellow tube sound. I had removed the tone controls from the PAS on the left so I may not have had a true sonic output. The PAS will stay with that mod and cap testing will continue, Auricaps or Illinois and maybe later another brand.

One down..! waiting for board parts to finalize the upgrade

Dynaco St-70

A set of Dynaco ST-70 with one upgrade finished the other needs couple of output caps. I think I will gut them after a sound check and nickel plate them as well. I am not satisfied with how the pitting cleaned up on the chassis.
I am going to test them as well with Auricaps I stock.

Pretty much everything is now in storage till after the summer months
