Gorgeous!!!!!!It's finally ready! There has been some delay because of transformer shipping times and me being sick but, here's Telemachus! More info on the website!

WOW! Can't wait for impressions from UT . A 300B with grid drivers, wonder if anyone else has done this.It's finally ready! There has been some delay because of transformer shipping times and me being sick but, here's Telemachus! More info on the website!
I see you managed to get Billy Joel in for the demo... :

Is this fully balance amp or SE like Infinity? And What's the difference with Infinity 300B in term of sound character?

Is it 5u4g rectifier? Looks really nice. I can not wait to read some sound impressions. How does it sound, would be super to have some comparisons

I was waiting to see this amp. Sorry to hear you were sick. Hope you have recovered ! So it is indeed called Telemachus, who is the son of Odyssey and Penelope in the Greek Mythology.
Congrats on another stunning amp. The Ultrasonic Studio product range have grown. I'm glad to see that it has a 300b amp in the stable.

Very nice. If I didn't already have a 300B amp, I'd get this one.It's finally ready! There has been some delay because of transformer shipping times and me being sick but, here's Telemachus! More info on the website!
"The 300B filaments have regulated 5VDC power supplies for lowest noise. The high voltage power supply can be made both unregulated, if you wish to use rectifier tube, or regulated using SS diode rectification and a Maida style regulator."
Can the amp be built with both, and some sort of selection switch to choose between the two?

Unfortunately the amp is for another lucky client. Yes a 300b with grid drivers.
Here's what Tomas told me in an earlier correspondence.
Tube rolling 6SN7 input tubes will affect the sound! But, they don't drive the 300b's. I have grid drivers in place for that! This is where the "modern design" comes in!
This unit he can only roll 6SN7 type tubes like 6f8g and ECC33.
Perhaps ECC32 as well... that's my guess. Tomas to confirm.
Looks soo beautiful !!
Is this fully balance amp or SE like Infinity? And What's the difference with Infinity 300B in term of sound character?
It's an SE amp and from what Tomas has produced, both SE and balanced amps sound great. Hard to say the difference in sound character between this and Infinity 300B but I'd say the difference will be very significant.
Far a start, this use Sowter output transformers and Hammond mains transformer. Uses Yamamoto sockets as well. Not doubt it will have boutique capacitors as well - probably Mundorf s/g/o capacitors.
Other significant difference is the choice of 6SN7 inputs that WILL affect sound.
Again in the words of Tomas
This gives Telemachus the best of both worlds. Fast transients and speed due to the grid drivers while still maintaining the beautiful 300B sound! This sound signature is one that I want to hear. It's probably what I'm looking for in a 300b amp.
Telemachus will be defined by it's sound more than any other aspect and with 12.5 watts into 8 ohms, yeah it's exciting. This should drive Susvara easy.

In an earlier photo that Tomas showed me, it was a JJ GZ34 rectifier. I think you can use both GZ34 and 5U4G here. Probably the other variants too like GZ32, 53ku, U52 etc. Tomas please expand on this?

I was reading this with interest too regarding the power supplies.

It's a SET amp.
Well those two amps have nothing in common really except they both use 300B's at the output. Infinity runs the tubes in their linear region at all times, while Telemachus let's the tubes operate in their non-linear regions as well. This gives Telemachus higher THD. That isn't necessarily a bad thing. Depends on your preference.
It can use both GZ34 or 5U4G.Is it 5u4g rectifier? Looks really nice. I can not wait to read some sound impressions. How does it sound, would be super to have some comparisons
Hopefully the client will share some impressions later. It shippes tomorrow!
Yes, definitely a possibility! Not switchable with amp on though.Can the amp be built with both, and some sort of selection switch to choose between the two?
Yes, ECC32 should be fine.Perhaps ECC32 as well... that's my guess.
It can use basically any rectifier that can put out 200mA. He shouldn't use 274B though as first cap is 10uF. The 274B wants 4uF as first C.In an earlier photo that Tomas showed me, it was a JJ GZ34 rectifier. I think you can use both GZ34 and 5U4G here. Probably the other variants too like GZ32, 53ku, U52 etc. Tomas please expand on this?

My current amps have quite a few switches where they are "not switchable with amp on though" I think the amp seller has to trust their customers when they agree to such switches. Would never see these types of things from off the shelf amp manufacturers.Yes, definitely a possibility! Not switchable with amp on though.

Is anyone on here getting this 300B amp? And if so, are you going to buy the new Western Electric 300B tubes? I have the Tak 300B on my Glenn amp, and I swore to never tube roll with this amp. Amazing I've kept to my word so far, but I have to admit I'm getting tempted by these new WE tubes.

The amp looks is starting to grow on me. I like it.
Tomas, what does Maida style regulator do? The ability to switch between solid state and tube rectification is very appealing.

I swore that Odyssey would be the last amp but now I have to sell off the golf sets, carts, Bcowen and Baronbeehive to afford this.
Dunno but a possibility for 2022. My mind's hatching plans now.

Tomas, take a low light shot of Telemachus with the amp powered on please. Those are VU meters and not mA meters.
