How about this one?:

Telefunken 12AT7
Bulgaria location - can take a month to get stuff from there! You can get good old stock tubes right here NA.....

Cheers,

Building a shopping cart right now, went for simple ceramic noval and octal tube sockets.

I am looking at the coupling caps. I see George uses Auricaps, but they are expensive although great without doubt. Can I do with Orange Drops or should I look for others?

I list the Auricaps and some other pricey caps because many builders want them.

I have found that they offer a small improvement in a TSE on a good system (good speakers, turntable, and quality transformers in the amp). I have one really nice TSE that does use Auricaps and Electra-Print OPT's and some 85 year old NX-483 output tubes. It is the best sounding amp I have. When I take it to visit my friends $20K Lowther based horns, it can hold it's own with some of his $$$ amps. The TSE is just a bit nicer sounding than a very low buck 6V6GT triode SSE on my Yamaha speakers.

I used some $2 generic white poly caps from Mouser in my SSE (Mallory maybe), and I have Orange Drops in my SPP, they are a good budget cap.

Hi George,

Hope you're well.

I am having a blast preparing the SSE amp, even getting into doing some of the chassis work. I think it's going to look good, perhaps not like a traditional tube amp, but more inspired by synth design. Hopefully, I can get some new pictures soon, the IEC plug hole has been a bit problematic so far.

Thanks for the info, I chose some cheap Solens from PartsConnexion, and hopefully they work well. The Edcors are definitely massive, so I went with a rather large amplifier chassis footprint for the SSE amp (partly inspired by synth modules and synths but also by an audiophile friend's Conrad-Johnson Premier and the Apple philosophy of leaving breathing space - this said, maybe the output transformers could be set wider).

So far, tubes are: KT-88 & 12AT7 by Electro-Harmonix, and a Sovtek 5AR4.

Is there anything particular that I have to take care with these?

Thanks a lot.

That's fun because I was just reading about Lowther drivers in a few articles about Nelson Pass and his Kleinhorns with Lowthers as well as current source amps.

Maybe one day I'll get around designing my own amp and speakers around these principles.

Back in 1971 I was awestruck by watching Keith Emerson at an ELP concert. I started work on a digital synth of my own design in 71. It got abandoned when I got a full time job at the local Motorola plant. I simply bought an Odyssey. Now 41 years later, I have been "retired" from Motorola, and have started work on my own modular synth. It will take a while, but I will post some of it once it starts making sound.

That's cool, George. There are a lot of good people on Muffwiggler and Electro-Music who share info. Sometimes there are fantastic PCB runs too for those who don't do their own PCB.

I started with a DIY frame made from an old suit-case, together with a computer power supply for tinkering for now, and the first module will be a Thomas Henry VCO-555. I am going to make my own interface for it as I would not like to use a modular where the controls and the wires are entangled.

Enjoy, and hopefully we'll get to make some cool music with our gear.

Member THeff on Electro-Music used to work with me at Motorola, and he lived a few blocks away. I saw several of his projects materialize. Unfortunately he got laid off about 4 years ago, got a new job, moved, and that company recently ceased operations, so we don't see each other very often anymore.

I have cut all the wood for a sloped front case that looks a lot like my old Odyssey. It will hold Eurorack modules, but I haven't built any modules yet. I am in the process of moving about 1200 miles, so I can't tell you where all the parts are right now. It could be a year or more, before I have my lab fully operational, but I hope to have something useful within a few months.

How the move going ?
As some know I lost my 41 year job at Motorola on March 31. My wife has always wanted to return to her home town, so we set out to move into the house her mother left her, one trailer load at a time. In early June we put the Florida house on the market, and set out for West Virginia in a 22 foot Penske rental truck loaded to within 150 pounds of max GVW. While we were unloading the truck in WV, we got a call from our real estate guy.....We had a contract on the house and we had to be out by July 3. So much for a slow orderly move.....now it's stuff everything in boxes and hope you can find it later. We should say goodbye to Florida around July 12.

Sorry to hear. I find it highly disturbing that companies put people on the street after 41 years of service... I am wondering how the responsible management can sleep at night.....

Just my 2cents
