DYNACO ST-70 6GH8A / 6GH8 PC-3 DRIVER BOARD PARTIAL KIT (PCB + Platinum Matched Pair Mullard ECF82 NOS NIB)

 

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 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 single layer board with solder rings at the bottom layer.  Solder reflow process is done at the bottom layer and blue solder mask is applied at the bottom side. 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 or we can provide it.

In this KIT you'll get one brand new PCB and one NOS NIB matched pair (two tubes) ECF82 Mullard in original boxes. Every pair is selected from the same batch with same date codes and tubes are real platinum matched pairs, tested on my calibrated METRIX U61-B tester.

Great Resource!
Format: Hardcover
The online resources are invaluable. The book came to me in a timely manner. This publisher does a great job at explaining legal principles and giving several examples of how the law is applied. I've enjoyed using it in my semester work thus far.

Digital textbook code already redeemed
Format: Hardcover
This book arrived unwrapped. Inside the textbook there was a return packing slip from Aug 2024 that someone forgot to remove. Unsurprisingly, upon checking I realized that someone already redeemed the digital textbook code that accompanies the book. I was sent an opened textbook that someone purchased and stole the digital code before returning.
