Conrad Johnson PV12 power transformer

appreciate the feedback everyone.  Juuuuuusst lookin for current rating on the heater winding on the transformer specified.  If anyone has this info would be much appreciated.

Using this w the phono stage otherwise would certainly have just pulled those tubes, cheers.

Curious to listen to e180cc’s in the output stage of a Pv12. Yes I know these arent a direct sub for a ecc82.

ECC82 filament current is 150mA at 12.6V and E180CC is 200mA, the difference is 50mA.

PV12 transformer can support total of 6 tube filaments, the line stage only only utilize 2 tubes. If your unit comes with phono stage and you only use the line stage, remove tubes from phono stage can save filament current.

There is a list of suitable tube substitutes.

PS - DIYaudio is a better place for questions like this I think. :)

In this particular context I would say that’s a lot of current.

A better and much safer mod is, IMHO, reducing the overall gain of the preamp. Sorry I no longer remember what is involved but I believe it's a resistor change somewhere.

Personally I would not do it....
