DYNACO ST-70 6GH8A / 6GH8 COMPLETE STUFFED PC-3 DRIVER BOARD (Retro Phenolic Look) WITH TUBES (NOS Platinum matched pair of 6GH8A EI Philips)

 

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 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 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.

This is complete board! One brand new PCB, ceramic sockets, Hi Quality MKP coupling capacitors, silver mica capacitors, metal film, metal oxide and carbon oxide resistors and one NOS matched pair (two tubes) of 6GH8A EI Philips. They are made back in 80s in EI tube factory, under Philips licence and with some of genuine Philips materials. They were intended for export, so they have passed strict quality control. 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.

All coupling capacitors are high quality MKP Metallized Polypropylene (PP) Capacitors. 120nF are used vs original 100nF, for a bit better bass response. Also silver mica capacitors are used, metal film, metal oxide and carbon resistors for good performance and lowest hum.

The best meat sticks!
Flavor Name: Wagyu Beef Steak, Size: 20 Count (Pack of 1)
These are the best meat sticks I’ve found so far! They are very clean and go down well. Very tasty. If you need more protein on the go-these are a no-brainer. Slightly pricey, but worth it!

Not bad. Read the box.
Flavor Name: Wagyu Beef Steak, Size: 0.8 Ounce (Pack of 10)
First of all, this isn't really beef jerky and nowhere do they state that it is. Simply put, it is not your typical beef jerky. I don't know how these are processed because there are not nitrates, nitrites, or even celery powder - which are the ingredients used for curing meat. Yes, these are ground and formed meat strips, just as it says on the box and on each individual strip wrapper. These lack all the extra preservatives and additives that other strips and jerkys have. And although some of the other meats that they have are flavored with cranberry, apple, or bacon, these don't have much flavoring at all. Just added honey, which keeps it from being totally vile. When I first opened the package, the scent was that of old time (not ancient) jerky. The way jerky looked and tasted in the 70s. But the flavor is really meaty/bloody tasting, with little hint of honey that makes it palatable. I'm not hating on this, it's rather not really too bad... just gotta get used to that bloody raw meaty taste. I've had their beef/bacon/cranberry bars and those were not edible. They were totally disgusting. Maybe it's because these are thinner and more like jerky (you get less of a mouthful) that I find them easier to swallow. I'v had quite a bit of their "bacon" bars (note, they are bars, not strips), and really wish they'd make the bacon bars thin like these strips as well. Although I like the bacon best, sometimes it's just too much... it's like spam but not as tasty. The texture of these is much better. Bottom line, if you expect these to taste like O'berto stips, then don't get them. If you expect something that tastes like a caveman's dinner, then this is it.

Meh
Flavor Name: Wagyu Beef Steak, Size: 20 Count (Pack of 1)
This is not beef jerky but rather and "ground and formed" meat snack. Not particularly rich, not particularly flavorful, and thus not particularly Wagyu.
