DYNACO ST-70 6GH8A / 6GH8 PC-3 DRIVER BOARD PCB

This is Dynaco ST-70 driver board PC-3. It’s developed and designed to be drop in replacement and it follows original wire hole layout, but it’s modified to use widely available and better sounding 6GH8 / 6GH8A / 6KD8 / ECF82 tubes instead of obsolete and hard to find 7199 tubes.  You can find many quality NOS tubes of any of these types for normal prices and you can enjoy tube rolling with this driver board.  It’s also modified to accept modern and NOS coupling capacitors of various types and dimensions.

It’s made of hi quality epoxy fiberglass FR4 material 1.6mm (0.062’) thickness, it’s double sided with solder rings on top layer.  Solder reflow process is done on both layers and also inside every hole and blue solder mask is applied on both sides. All connections and elements on the board are silkscreened with original DYNACO numbering, so you can use original DYNACO ST-70 manual to complete it.

Pure 100% Cashmere Beanie for Men - runs very small.
Size: One Size, Color: Black
A soft cashmere which is ribbed. However it is advertised as a Mens hat but size is very small for a man. Would be a better fit for a petite woman. Looks here like it has a turn up ribbing at bottom, but it does not.
