Does anyone need custom power/output transformer?

lem8r · 12th January 2010, 09:43 AM

You can order toroidal transformer build by you own specs.
All transformers are carefully hand wired at Tornado factory in Ukraine.

For example power tranny for 100W guitar tube amp (Plate, bias, heater voltages) would cost about 80-100 USD + shipping to US about 20-25 USD.

Higher power rating are better priced)

Here is mine 600VA power transformer for 6x6550 amp( cost me 180$ ) /crappy cell phone photo/

on a test board:

some other transformers:

For output transformer you should specify Plate-to-Plate load, B+ voltage, Power rating, Bandwidth, Secondary winding configuration etc.. I can help you with calculations..

So, if you are interested just PM me, I give you all detailed info..

Have a Nice Day!

You might want to put some rubber gromets in t hose holes to protect the wire insulation.

Yes, I agree it's not good, but it is only test board. As soon as I get my OT I'll move all this stuff to far more better chassis..

In any case you're right. 700V it's not a jokes..

I must add to this thread.

I have, for multiple trasformers, taken advantage from lem8r's source of poer /output transformers.

Here are some pics:

low voltage high current toroidals for large transimitting tubes, huge mercury rectifiers and HV transformer for all high voltages in a gu81m amp.
The construction is flawless, the transformers are exceptionally good underr load and show both low vdrop and excellent symmetry.

I will be using the output transformers too. I will then post frequency response plots to check the quality.
Lem8r is a great guy and will be a perfect middleman (if required).
