 I plan to build my last esoteric SET amp.

Which driver for Da Siemens Post Tube?

(Da is a 1 W tube, enough for Avantgarde Speakers.)

Original schematics for German Post Tubes are impossible to find.

In my collection I have these to choose from:
Ca,Cd,Ce,Cf,Ec,E2,Ba,RE134,3A/110A,WE102D,C3m,C3g and more.

 Hi,

do you think it is worth copying old schematics with outdated bandwith ratings? They are interesing tho. And very hard to read with all wiring drawn. I have seen one Siemns 1930ies Da amp with all testpoints wired to elsewhere.

A Ba requests for 25k 1:1 IT, Aa is ven higher at 30k. Z2b rectifier mates nicely.

Will you sell a pair Cd tubes?

kindly,

Anton
