CSS for 6c33?

[rvrazvan]

Not far from now i will have all my parts for a 6c33 SET amp. Just neeed the transformers and the driver tubes. Does anyone around here have any experience with CSS and 6c33?
How does it sounds? Is it reliable or it will just make my life a living hell?
Any schematics ?

What's CSS?

Sorry ) CCS ).

CCS plate loading of output tubes has been discussed in many threads. I would say most users are disappointed by the big penalty in power and favour choke loading instead if going the parafeed route. What are you planning to use as an output transformer?

It's a custom made transformer, made here in romania.
Ra=600Ohms
Fmin=28HZ
Max power=30W
Capacitance=2700pF
Iamax=600mA

Looks like a single ended OPT. Why do you want to use it in parafeed?

Just testing . I might use one as a choke and the other as output.

Using an airgapped transformer for parafeed purposes defeats the purpose. What you get is an amp with an extra capacitor and none of the advantages of a real parafeed output transformer.

Just build a standard SE amp instead.

If the output transformer is parafeed. Then yes. Using the primary of a standard airgapped output transformer should work quite well as a plate choke.

I'm just gonna play with parafeeding. The transformers will be used as they are suposesd to in the end :P.
