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.

Fun but not for rough play.
Color: Orange
The ball contented our “golden” Jaxson for about 15 minutes. He then thought it was a regular ball and it’s just a little delicate for a big dog. I just wrote it off as a loss. Great idea but should be more durable.

My 50 pound goldendoodle absolutely loves this ball. It keeps a charge for a long time. It turns off When it’s not being used and we play with it every day.!

Great toy. Definitely worth it.
Pattern Name: Classic Squeaky Tug, Pattern Name: Classic Squeaky Tug
This is a great toy. I bought this for my dachshund, and it's still going strong after 2.5 years. The string part came off after a few months, but that's fine. This is always her go-to toy.

Perfect so far!
Pattern Name: Classic Squeaky Tug
My dog has a habit of tearing up toys in just a few minutes, so far, this toy has lasted a few days, the rope is already showing signs of wear. I wish there was a way to attach a new rope when this one goes... She is a mid-sized dog with a LOT of energy, and she's very destructive, digging, chewing on things she's not supposed to, etc. This helps with that, she can play with it for a long time, we don't have to always 'check' to see if she is tearing something up. She loves grabbing it by the rope and swinging it around the sides of her head, it doesn't hurt her, and she LOVES this toy. Out of ALL of the toys that we have bought her, and that she loved, THIS ONE has been top dog to her. We love watching her play with it, it also wears her out and she'll then take a nap, which is always good. Oh yeah, the size if PERFECT for a mid-sized to a large dog, I'm not sure about any smaller dogs. She can squeak the squeaker on it fine too, but not at first, she had to 'find out' how to do it on her own. As far as chewing it into little pieces like one person has said, I can't attest to that, and I hope that is not the case. I will return if she does end up chewing it into pieces, because she in known far and wide for that! :)
