Hello

This El GEC-30w looks really nice, but I think it´s a bit out of budget for Grabo want to spend the minimum. But if you want some traduction I can help you
NO PROBLEMO.

Hi Pascal, Icare,

I don't know about the modified GEC 30. As with most amps I believe a big part of the final quality comes from the OPT used.

Which somehow reminds me of the Jadis JA30, the Yves Cochet (Cl AB1), idem for the Ampliton etc.

As for Grabo, why not do a Curcio mod on a Dyna?

Cheers,

Here is a low cost plate voltage transformer for DIY projects, $20:

http://www.meci.com/

(click on transformers, then click on "standard")

Its the first one that comes up, P/N 600-0427 made by Hammond.
Actually is a 300 Watt unit for normal temperature rise (the 500 W rating is for smoking hot temp. rise), weighs 10 Lbs, 120V to dual 240V windings. No electrostatic shield, so use a line filter with it. The fuse holder on top is removable. Make sure to enclose it in the chassis or a box, for safety, since it has exposed terminals.

Hello Frank, thanks !

I don't know if for USA it is possible to buy, but for europeans, i recommend Magnetic main or output transformers http://magnetic.com.free.fr/ . Very very good !!! and low price. They are near my house and I know them very well, if you buy transformer say that ptsoundlab recommend you, it is possible that you have a better good price

Cordially

Pascal.
