Looking for circuit of SE amp. for Eimac 100TH - Page 2

head · 8th January 2007, 09:23 AM

I just got hold of 2 100TH's too.
Had a look at Astouffers diagrams.
The 6EM8 should be a 6EM7...
Can anybody tell me what kind of output transormer this is??

Thanks!

Hi Eimac

check out this link: www.triodefestival.net/uploads/.../michimori%20(PPTminimizer).ppt
this is a cool way to drive the A2 tubes, if you don't like to use a FET.

best regards

Hi Karsten,

A friend of mine built an 811A SE amp adopting the regulator tube drive method to achive 22W output succesfully. He used a SOFTON R-core output transformer.
I think SOFTON RW-40-5(40W) can be use for a 100TH SE amp.

Hi Michi-san,

BTW are you comming to the ETF this year? please bring a the 8025a amp to the ETF.

Karsten-san,

I found some of their english Catalog. I am now asking them English catalog of RW-40-5.

I am afraid, I can not come ETF2011 this year. I hope I will join ETF2012 in Denmark? As I have many old friends in Copenhagen.

Best regards
H. Michi

Kwan-San, long time no see! Hope you are doing OK.

BTW a friend of mine built a 811A SE amp with the regulator tube drive, and the OPT was Softon RW-40-9.5. He used 5K ohm tap and 16 ohm KNF for his 811A amp.

Thank you

I have just received an English Catalog of RW-40-9.5, which is almost same as RW-40-5.
