help.............

let me add, i am in a position were there is problems with the electrical grid. they had to replace the transformer just resentley, and it seems the problem with my home is starting up again. i think there is a ground problem that they dont want me to know about. i was getting feedback of current into my house. i notice when they put in a ground the loudness came back. thats why i stated earlier that i might need a conditioner.........

The original PV10 used 12ax7, 12at7 and 5751, tubes with much higher gain than the 12au7.

You may want to cal CJ with the serial number and ask about the correct tubes for your unit.

Good luck

thanks, ill call ed and ask. i think my came with the ecc82's.

tanks beth, nice to get advice from a female on this topic. so you are saying that 12ax7's wont hurt. another post suggested 6922 amperex.
