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.

It fits, but just barely, so it's good that it is sturdy
Style: Matte Black Single Slat, Size: E46(2002-2005)4-Door, Style: Matte Black Single Slat, Size: E46(2002-2005)4-Door
First and foremost, this part is a fairly poor copy of the OEM part. It's close enough to look good from about 20 feet away, but on close inspection, it has gaps all around. It doesn't follow the curve of the opening properly, and the contours aren't quite right, making it so the outer top corners aren't recessed the way they are supposed to be (see pictures). Some of the tabs don't interface with their mating surfaces because the part is about 5mm too small in the y-axis (see picture). That said, after ordering another similar knock-off, this one is the better of the two. The matte finish is truly matte. The grill slats are thick and beefy, like OEM. The tabs are stout and flexible, not brittle. After much fussing with installation, you should be able to bend your hood tabs (not that you should have to) so all tabs will lock in place. The hardest part for me was getting the outboard-most tab to properly snap in, since the outer top corner of each grill doesn't sit flush inside the recessed relief where it's supposed to sit.

Why pay OEM prices? These kidney grills fit excellent!
Style: Matte Black Single Slat, Size: E46(2002-2005)4-Door
Was a bit skeptical but the fit and quality are excellent. The do not wobble around or fit loosely. Highly recommended.

Easy replacement and noticeably fresher air
Size: 1-Pack
Installation was quick and simple, and it fit perfectly in my vehicle. I noticed an immediate improvement in the air quality inside the car. The activated carbon helps reduce odors and keeps the air feeling cleaner and fresher, especially during everyday driving. The filter feels well-made and durable, and it does a great job trapping dust and debris. It’s a simple upgrade that makes the driving experience much more comfortable. Overall, this is a great quality cabin air filter that delivers reliable performance and excellent value. Definitely recommend!
