Nickel transformers have arrived -- I am listening to them right now. Now it is just a matter of getting the first batch to Tom and getting the site ready to take orders. Almost there.

What are your impressions as you listen to them?

 

[dsavitsk]

They sound just like the prototypes, which is to say they sound fantastic.

 

[FishHead]

It is always nice when a production run works the same as a prototype.

Bump . Not that I am VERY interested and check every day or that I would admit to doing so.

Oops! Nevermind.

The kit is available.

Are the cinimags a viable upgrade for the T1? If so what would you project the difference being?

The ones my mate order just arrived. I should get a chance to hear it a bit.

I made adapters for 6E6P tubes
 

 
First I tried 6E5P tubes and liked how they sound, but heaters resistance was so low it triggered heater regulators overcurrent protection when tubes were cold.
To get around this I turned amp on with one tube plugged in and let tube warm. Then turned amp off, plugged second tube in and turned amp on again.
6E6P tubes dont have that problem and also sound good.

I have also wired output tranformers as autoformers.
 
First I moved primary GND tap to unused pin next to old pin.
 

 
And then used jumper wires to connect it to 300 ohm pin.
 

 

[OJNeg]

Huh, interesting idea. Would you mind giving us a quick sketch of how you changed the XFMR wiring from the schematic view?

Am I late to the party?
Yeah well, I´ll try anyway. Bought the blue Torpedo a while back and want to do some of the tweaks, lots of hum; so I have some questions related to materials.
The BY228GP (DO-201AD) Rectifier 2.5A 20V, I can´t source these in Europe right now; I can get 1N 5822 Schottky Diode, 40V 3A DO201AD from banzai, can anyone give me a few tips?
The zener mod, I got zeners at home, 6.8 and 7.5v, not the one listed though. No RN60 resistors but ordinary 1% metalfilm at 430 and 470r. How crucial are the VDs?
I now it´s an old thread but it´s all I got, very appreciate of any help.
