I have one or those Monster avs2000 for sale at videogon. great price. It should do the job.I love that it tells the curent draw and the amount of correction. Sorry for the shameless plug.---But, it sounds like you do need one of these--- mine or somebody elses don't matter. I should have mentioned---contact Judd, I'm sure he will tell you what you should or shouldn't have.
Voltage regulation for Joule amps
I am wondering what if anything others are using for locking the AC voltage for their Joule amps. Based on the built-in voltmeter, my AC varies substantially, when I have the variac set for 89 volts and then the output tubes biased at 27-28, I find that it can be down as low as 82 volts as short while later, with the bias dropping down to 22-23!! I do not have the amp on a dedicated line and can try that next, after the XMAS lights are gone, but I'm betting it is a problem with the power delivered to my house. The difference in price between a Monster 2000 and an Exact Power 15a is almost $1K!! Any thoughts? TIA and Merry Kwanzachristmakah>
