Let's see your tubes!

It's hard to believe that such a big output transformer has bandwidth that good! How much do they cost to purchase?

Not a problem. As most of you know I design my own transformers and then have them made for me. The transformers for these amps of course are single ended.
These particular transformers are rated for 200 watts! They can take 600 ma dc in the core and they weigh in at 65 pounds each!!! The measured bandwidth @ 160 watts output is -1db from12hz-47khz! This is with 3KV on the plates. They have 4 and 8 ohm taps.

Those cost me nearly $1K for 2 of them. In single ended operation it takes a huge amount of iron to achieve a good clean low end! Winding technics have a ton to do with the good hi end response. I will not disclose my winding specs!

Do you have picture of them? Are they available for diyer to buy them?

ABSOLUTELY not available to the diy market!!!

I am not going be responsible for someone vaporizing themselves!
I have had extensive workings with voltages up to and above 100KV capable of several amps and the high voltages do not bother me. Sorry I will not let these out for sure!

The 3Kv supply for these is capable of well over 2 amps, definitely lethal! The caps are 100uf @5KV laser pulse caps capable of delivering pulses in excess of 5000 amps!

Deadly stuff for sure.

Hey!

Sound like a mad sciencetist's project.

Take care,

EL-156 tube. Plate dissipation is 50 watts but no cherry plate at 65 watts.

Super clean, harmonically correct. Dimension is fantastic. Amazing sound quality.

Well, I guess I just have to listen to these:

Have not hear this tube playing for a little while.
Just hook up and playing. WOW

Here's my Image 65i.

Here is a pic of my recently completed Bottlehead Stereomour configured as a power amp. I just received the JJ 2a3-40s, what a difference a tube makes, even with no time on it. I tried to take the cool pic with glowing tubes, unfortunately the only tube on this amp that glows enough to show anything is the JJ ECC81. I will try again when it is completely dark, for now here is a pic with the JJs installed:

Happy listening!!

The 2A3s don't glow a lot so a shot in the daytime

Ahh....so that's your amp pictured on the Hawthorne site. I wondered who owned that. I think it looks likes like a caboose.
Very cool.

Yes Bob, that is me spamming the net with my latest project. I hadn't seen the caboose but now that you mention it I do. Well, my dad worked for the railroad for 30+ years so a caboose is appropriate (of course I think they had already done away with cabooses, caboosi(?), whatever, by then).

Best,
Ed

Bob in St. Louis · « **Reply #73 on:** 7 Jun 2011, 12:20 am »

Actually, I saw a caboose in action the other day.

WTF??? Really??

Anyway, there's a profile shot of the amp on the Hawthorne site that really drives home the whole caboose image.
Not to detract, actually I love it. Great stuff Ed.

Bob

p.s. Oh...No worries about spamming the net with your newfound pride and joy.
You should see me spamming my new RiPole build.

As a financier, if you were a public company and offering said amps to the DIY communtiy, you'd be my first short. That is to say, I completely agree with you.

Audio Mirror Series Eargasm - 45 Watt SET monoblocks - parallel pair of 6C33C output tubes per monoblock with NOS Sylvania 6SL7GT and 6SN7GT (input and driver tubes were swapped in after picture was taken).

Whoa! that is one slick looking amp. Quite elegant!
