DYNACO ST-70 6GH8A / 6GH8 PC-3 DRIVER BOARD PARTIAL KIT (Retro Phenolic Look PCB + EI Philips 6GH8A Platinum Matched Pair)

 

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) of 6GH8A EI Philips in original EI boxes. 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.

Love the color, and texture of the blanket. Great price too!
Size: California King, Color: Peacock Blue
We have this blanket sandwiched between our top sheet and comforter. My husband feels nice and warm with the blanket, but I'm a warm sleeper. I feel comfortable also since a keep a floor fan aimed to my side of the bed. Problem solved and we both get a comfortable, good night's sleep.

Soft, Luxurious & Perfect for Hair and Skin!

These satin pillowcases are honestly amazing. The material feels super soft, smooth, and cooling on the skin, and they make my bed look so elegant and luxurious. I bought them mainly to help protect my hair from frizz and dryness, They’re also very comfortable to sleep on and don’t feel cheap at all. The color is beautiful in person, exactly like the photos on Amazon. I washed them already and they still kept their softness and shine. Definitely worth the purchase for the price I would 100% buy again and recommend to anyone looking for cute, comfortable satin pillowcases.”

Budget friendly satin pillowcase
Size: Standard (20" X 26"), Color: 18 - Lavender, Number of Items: 2
This satin pillowcase is a great budget-friendly option! While it’s not quite as luxurious as my Blissy pillowcase, it still does a really nice job—especially for the price. It has that smooth, silky feel that helps reduce hair frizz and feels gentle on the skin. It’s also easy to wash and holds up well, which is perfect for everyday use. I especially love using these for the kids—they get the benefits of a softer pillowcase without worrying about ruining a more expensive one. Overall, it’s a solid, affordable alternative that still feels nice and does the job. Great value and perfect for families!

Super soft and durable, but keep your steamer handy!

I’m really impressed with these grey satin pillowcases! First off, the packaging was adorable, making them feel like a little treat to unbox. The texture is incredibly soft and feels great against my skin. In terms of maintenance, they’ve held up perfectly through the wash. I followed the instructions (machine wash on gentle cycle and tumble dry on low/fluff), and they came out looking as good as new. The only real downside is the wrinkling. Even when I remove them from the dryer promptly, they tend to wrinkle pretty badly (see attached photo). If you don't mind a quick steam or a few creases, these are a good value!

Fantastic satin pillow cases for the price
Size: Queen (20" X 30"), Color: 02 - Pure White, Number of Items: 2
Edit: I already put five stars in the first place, but I was unfair to these pillow cases in my initial review! I thought they were a little warmer than the natural silk, because I was sleeping on them with acrylic pyjamas on. I have come to realise the pillow cases are not warm. They are truly excellent in every way. I just get sweaty every time I wear acrylic pyjamas! I have already ordered two more sets of these (and have switched to micrfibre pyjamas)! Original review: First off, I want to address a popular misconception. Satin is a weave, not a fibre. So polyester satin is real satin, and it is very common. To all the people saying the makers lied about the fabric, they absolutely did not! I bought these and I bought some inexpensive silk ones at the same time. I have been loving the silk ones and only started using these lately. I'm happy with all of them. These are not silk, and I can feel the difference, but they are a nice, smooth polyester satin. The white colour is indeed a pure white. I machine washed mine and hung them to dry. They did not wrinkle, pick or pill, and they did not change in colour or size. They look fresh and pristine. I measured my pillows and got the right size. They are pretty and neat, they seem to be well sewn and well finished, with no hanging threads. They are very soft to sleep on and did not make my dry, curly hair frizz up. I slept on them without my protective bonnet, so I got the full experience! Honestly, with the smooth, tight weave of the fabric, they may be superior to the real silk in terms of babying my skin and hair. However, they are a little bit warmer. That is fine for now, since the weather is cool. I might just use these while it is cool out and switch to silk in summer, or I might continue to alternate, we will see. Overall, I am happy with my purchase and would buy them again.
