Knowing the affinity many here have for the ART-13/ATC, thought this mind be of interest:

http://tinyurl.com/38vwscd

Some will remember that, along with the ART-13, they also copied the BC-348 receiver as part of the project to copy detail for detail the American B-29 from three examples that made emergency landings in the USSR from missions to Japan, including the Hap Arnold.

You gotta love the guy's description.

Looks like someone hit the vodka when they made the silkscreen - some of the lettering is backwards and inside out... Wink

And P is really R or whatever. Smiley

It's a pretty amazing copy considering they had to reverse-engineer it to build jigs, molds, etc. Almost as amazing is that this particular one was built in 1970. Around the time a lot of hams here were probably starting to toss their surplus ART-13s for new transceivers.

Garys_lab is a real trip. He has some great descriptions but I do feel that his prices are a bit too much. The equipment he has for sale is quite interesting though as some of the engineering on some of the Soviet communication gear is really quite impressive. Considerable lengths were taken in order to ensure reliability and durability.

What does the control labeled "Kaopectate" do?

It means Corrector. Корректор (Cyrillic). What does it mean, I don't know.

Speaking of BC-348, it was also copied, Russian copy was called УС-9 (US-9). As far as I heard, the entire machine including everything inside was copied by direct order of Stalin himself. People were afraid to argue, so even some extra holes in RT-13 were copied. The holes were made by bullets of Japanese machine-gun...

Thank you guys! It is nice to see you again!

All that time I had worked with audio only... Have some prototypes, but can't find a brave man who can take a risk and start manufacturing.

Here are some examples:

That's absolutely true. Several bullet patches were replicated on the B-29 copies for exactly the reason you say - no one dared do otherwise.

Good to see you back, Tolly - that's some nice looking equipment you've made! There has been a lot of new audio gear coming on the market in recent years, so persistence will be the word of the day.

Yes. But what they were not afraid of, to improve if improvements were obvious. For example, US-9 is remote controlled.

Tolly, A friend who manages a cigar shop goes regularly to Montreal to what I would estimate to be a really high end audio shows and shops. I'm probably preaching to the quire here, but do you go to such shows to network?

One of the items he purchased was a stereo preamp. I haven't seen this equipment in person but i did see some pictures of his set up.

The preamp had from what I could see had four 6SN7's in there plus some other tubes. It had a beautiful wooden cabinet and was all point to point wiring. Now the kicker, the cost of that preamp was $8000.00 big ones. He must have well over 100 grand in his system. I know we beat up on audiofools all the time but I say, if you can afford it and it makes you feel good, do it Grin Grin Grin

If you calculate how much it would be to manufacture in US or Canada... Oh boy! Chassis only would cost more than several Chinese amps... We can't compete against China, unless we have some exclusive quality that they can't offer.
For example, my Pyramids amps clip at 100W per channel, but optical limiters won't allow more than 80W. That means, never clipping on any peaks. I use high quality American made line input, output, and power transformers. Each of them costs more than entire Chinese tube amp. Point to point wiring, how much time of qualified work it requires? Can Americans be paid for such job equally to Chinese workers? If I calculate fair prise for my amps made in USA you will see that $8,000.00 preamp is not bad... Unfortunately, our modern economy is not favorable to Made in USA stuff... I call it Recyclonomics, only goods made for recycling can be competitive.

Do you mean, it's about time to start manufacturing in U.S.? But who can afford such production? And who is brave enough to invest in manufacturing of U.S. made gear?
