DYNACO ST-70 6GH8A / 6GH8 COMPLETE STUFFED PC-3 PHENOLIC LOOK DRIVER BOARD 

 

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!

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.

Great no frills watch, love it.
Color: Blue/Black
This watch is a really nice and is perfect for me. It tells the time (duh!), the date and has a stopwatch feature I never use. Mostly I like that it is a no frills product, but it does its job. This is great for people that actually want something that tells the time and not some fancy gold bracelet to impress the ladies. Although I spend most of my time in front of a computer, I imagine this piece would be great for someone with an active lifestyle (biking, running, etc.). The watch itself is mostly plastic and watch-proof and the band is a fabric velcro. For a while I had the older model with a rubber strap and I like this new model much better. The strap is comfortable and easy to take on and off. I wish the strap was a little bigger though, it might be too small for someone with really fat arms. It does have an indiglo feature although I had the older model and the indiglo died after like 6 months. Hopefully this one will last. What can I say, its a watch. If you are looking for something simple with a classic design, look no further.

Everything I expected.
Color: Black/Red
Not the watch I would want as an adult but fits my son perfectly. It’s durable, red and makes him happy. It should last him until he is old enough to get a job and make his own style and life choices.

Timex now poor quality
Color: Blue/Black
These watches used to last me years. The past two of these have died in under 6 months. Worthless junk. Will avoid Timex from now on. A single drop of water and the button sends the watch into black screen and reset.

Good basic digital watch for women
Color: Black/Gray Stripe, Color: Black/Gray Stripe
Okay, so it's a great watch for women with small to medium wrists. Here's my pros and cons list: Pros: - Super easy to set. The package insert does NOT include instructions. This is my first Timex Expedition watch, so I had no experience going in. All you do is press Set and you use the Start and Stop buttons to move up and down, respectively, through the settings. Easy enough! - I love the simplicity of the watch. It's simple and easy to read. - It has the day of the week AND the month AND the date. I wanted to make sure any watch I get has these features. - The watch band seems high quality. It is fabric/nylon, so it should hold up for several years (we'll see I guess). - The Indiglo is pretty and works great in the dark! Cons: - I have to tighten the band as tight as possible in order to prevent the watch from wobbling around my wrist. It may be because my wrist is small and the watch itself is a bit heavy in comparison. I AM new to wearing a watch, so maybe it's just something I have to get used to. - The display is perfect, but only when looking at it straight on (when facing you directly). If you were to glance over at your watch while you're typing on your computer, you can't see the time. It's too blurry. So the viewing angles are terrible. You can only see the time if you look directly at it. Again, this might be an issue with all digital watches, but I sort of expected more in today's technological world. This is probably my biggest con and biggest disappointment. - The band holder is also nylon, so I had some trouble getting the extra band into the band holder. Now that I think more about it, I'm not sure what a better alternative would be for a nylon band... maybe if they glued the band holder on to the band, it wouldn't move around so much when trying to insert the band into the holder. Once you're inserted it, it seems to stay in place, though. So that's good. But I can see it loosening up and not working well in the future. I've only had this watch since yesterday, so I haven't been able to test its waterproofness yet. I will update this review if I am unhappy with the waterproofness. Overall, it's exactly what I was looking for: a basic digital watch that shows the day and date, with a band that is small enough to fit my female wrist. However, I would have liked it better if the price was $10-15 less than what I paid for it. UPDATE: I've since moved on to a few other watches since this one. I have concluded that I do NOT like having a cloth/nylon watch band, and I prefer the rubber/plastic bands now. The nylon band takes way too long to dry after a shower, whereas the plastic bands don't need ANY drying time. There are a lot of good plastic banded watches out there, and I've tried a few no-name brands on Amazon and have been happier with them than I was with this Timex. They are also not as heavy and floppy on my wrist.

Comfortable, stylish, and great for work or casual wear
Size: 36W x 32L, Color: Black
These DKNY slim fit chinos are a great balance between comfort and style. The stretch material makes a big difference — they move well throughout the day and don’t feel restrictive like some other slim fit pants. The fit is modern and clean without being too tight, which makes them easy to wear for both work and more casual settings. They look polished enough for the office but still comfortable enough for everyday use. The fabric feels good quality and has held up well so far. They don’t wrinkle too easily and keep their shape after wearing them for a full day. The 5-pocket design is also a nice touch, adding a bit of versatility compared to more traditional dress pants. If I had to mention one minor thing, it would be that sizing can feel slightly snug depending on preference, so if you’re between sizes you might want to consider sizing up. Overall, really solid pair of chinos — comfortable, versatile, and good quality for the price.
