Conrad Johnson PV12 power transformer

Curious to listen to e180cc's in the output stage of a Pv12.  Yes I know these arent  a direct sub for a ecc82.  Main question is can the transformer supply the extra 200 mA needed, melting down the heater supply isnt worth appeasing my curiosity... 

My unit is from 1998 and the info on the power transformer states "783P8 MOD.  783P13, EIA-17-9715-4A". Google has turned up no info about this transformer unfortunately. 

 

any constructive thoughts on this which directly address the needed 200 mA are appreciated.

 

thanks

Personally I would not do it....

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.

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