Re: variable heater voltage
Well guys I've taken your warnings into consideration and I just had to try. I wanted to vary the power tube voltage from 0v to around 6.3v. to see how it affected the amp's volume.With a FWB rectifier and a 4700uf cap I got about 7.3vt DC across pin 2 and 7. The 2 6v6s are wired pins 2 to 2 to the ...

Re: variable heater voltage
Thanks for the reply K. The problem was a soldering error. (poor eyes and poor lighting in a poor work space) works just fine now. Thanks again for the helpful information K.

variable heater voltage
I would like to be able to occasionally lower the voltage to the power tubes only ( 2-6v6 ) to act as a master volume. As little as I play I am not concerned about stripping cathodes and tube life. My 12sl7 preamp tubes are running on 12 volts DC from a small 120 volt AC/DC regulated 12volt + - supp...

Asteroid power string
I have looked at the pictures of the Asteroid but I can't figure out the order of the power supply. Is it choke-1K-10k-10k ? Any help please. Thanks

Re: primary impedance for two 12sn7s - two 6K6s
Thanks for the screen information. My house voltage varies upon the time of day and I now get 360 on the plates before every AC unit in the city is running full time. Later in the day it will be around 340. It's been 95 - 99 degrees where I live. I measured the plate voltage at 360 and the choke fed...

primary impedance for two 12sn7s - two 6K6s
Hi all, I have a project for a push pull using two 12sn7 power tubes ( each tube is wired in parallel ) My power transformer is 340 volts on plates and my output transformer has a 6.6K primary. I have one speaker jack at 4 ohm and one at 8 ohm. The speaker is 8 ohm. I also have two sockets wired for...

Re: Another Asteroid/K60 Build
Sorry for this brief interruption but is there a schematic for the power amp section or could someone tell me the capacitor values for the Asteroid? I can't seem to figure it out from the layout. Thanks for any help.
