Beautiful! What speakers do you run with this amp? About 3/4s of a watt, if I'm not mistaken?
Just missed a Toshi Kurashima using 371s, 19s and 380.

I picked up a nice 45 amp with Tamradio OPTs made by Oliver. He gave it to me for audition for a week since I am local. It sounds really nice with my SAP Trio speakers. By the way his workshop is cool as well.

Is the first pic a pic of his workshop?

 

[Faust3D]

Yeah. It's also an artist studio and woodworking space. It's in the old canning factory in Brooklyn. Very cool place, check out this door.

 

[Limberpine]

Wow, so he voices the amps on those speakers. Are those original WE horns? Is he using WE drivers?

 

[Faust3D]

Yes, I think these are WE speakers and woofers are field-coil.

Do you know which Field Coil Woofers?

Cool as hell

 

[Faust3D]

Sorry, he told me, but I forgot. I have some stuff that I might have him repair for me, so if I talk to him next time I will ask him. I know he was running them in open baffle and was not completely happy with the bass response in the huge space that he has. I recall he told me he will be moving soon anyhow. This 45 amp that I got from him is really nice, sweet sounding. I am curious how it would test on the bench.

 

[Limberpine]

I have a 45 from him too. A Korneff clone. I will have to swap it in tonight and see how it sounds with the latest iteration of my speakers. I've been running a 6a3 DC coupled SET amp for the last 6 months or so.

Does 6A3 sound like 2A3? I never had an amp based on that tube. The amp that I got from him is a very simple two stage all triode amplifier using 5842 driver tube. Very sweet sounding, yet clear and punchy. I heard 45 / 2A3 amps costing 2 times as much that did not sound nearly as good.

Yes, similar to the 2A3. I can also run a 6b4g in that amp as well.

My Sayes is a 45 with a 7193 driver and 80 rectifier.

 

[Mr. Bissness]

Here’s my new to me SET 71a. Wonderful sounding 3/4 watt amp. Driving a pair of Altec monitors with ease.

 

[jmolsberg]

beautiful!

 

[jaipre]

Congrats @Mr. Bissness. Beautiful piece!
Wondering what’s the rectifier tube and transformers…I’m going to have Oliver to build one.

 

[Mr. Bissness]

“The transformers are OS Japanese made, probably OEM Tamura, believe the outputs were pulled from some 60’s pioneer equipment. Rectifier is EZ81 and driver tube is WeCo 407a input sensitivity ~0.8v for ~0.75 watts output (8 ohms)”

 

[jaipre]

@Mr. Bissness Is there a reason for EZ81 in most of his 71A he went with 80. Just curious

 

[Mr. Bissness]

Not sure. I purchased it from another HFH member and this is what it included.
