You should wait for 1min until the server gives green light. Else, provide Tea with your email to send it to you. Its ~1.8Meg, it does not load up here.

as I understand you do not recommend IRF 240 / 9240 as a hot road but IRF 520 / 9520 ?
where can 2sk117GR be sourced

[Salas]

No I don't recommend 'em if you want it to play as intended. 9610/9530 as in BOM. For K117GR Ebay has plenty. For typical shops I did not query.

Salas,

Thanks. Will do.

Remote sensing is a good idea Salas, all well done :- )

Thanks

You can use the two +V sections from the triplet for double mono B1 is another possible use. Download and read the guide, says everything.

If it helps-I can order a good deal of the 2SK117 GR's. I should be able to sell them for .50-75 cents each. I am also considering getting some of the needed transistors, and 1/4 W 1R resistors on hand, as these seem to be PITA parts to locate for some. I would not mind a show of hands so to speak what and who would like this.

I put for two boards in the spreadsheet, I would be interested in any of the hard to get parts you can supply.

I have put a copy of the build guide here.

The formatting may not be perfect. but it's up there.

I have found a seller that has the 2sk117 and diodes, pots some fets etc for good prices with low shipping charges, I have used them before and recommend them. Tayda Electronics Home Page. Pitty the irf9540 is not recommended, they don't have the IRF9530, but have most all other semis.

Will play with 9540s too, but the Zo bandwidth will close in and curve up a bit. On the other hand the minimum Zo will be 20% less. If you have and want to put, you can certainly see for your self.
