Can anyone please help on finding information/tube data on PTT100 and Ptt205 german post tubes made by CSF. I don't recall seeing any discussion in these tubes. Many thanks in advance.
Thanks for the information.
I onced saw a website that has a circuit which used the Bi as driver for the Px25 but I cannot find it anymore. The article mentioned that the Bi can also used as small power triode (0.5W??)and the sound was heavenly.
BTW, DHT Rob used a lot of post tubes in his design. Go to google for DHT Rob and you'll find it.
Yeah, Rob I don't know personally, but he is a fellow Dutchman for I too am from The Netherlands!
Here you go:
Also you may look for instance under TS32, an equivalent.
Just got 8 of them today which I plan to use as drivers for various power penthodes and beam tetrodes such as KT66 and 6384 Bendix, though not permanently but in amps that will be adaptable for many different tubes. Not there yet, but I am hoarding tubes for the purpose while waiting for transformers. So if you find you don't want the PTT100's I would want them. Only two of the eight I just received are CSF (which by the way was a French manufacturer, not German), so another few to match up into a quad would be great :~) I like the metal sleeve, gold layered pins and mesh anodes. The others I have are by RT (also french: La Radiotechnique) and feature bakelite bases, tinned pins and box anodes. Still beautiful sturdy big tubes with lots of appeal. I do not know from experience, but from the specs I should think these tubes would sound great in the right circuit!!! Cheers, Aaron
