Hey Kevin,
Thanks for the reply. I understand you advising against tube pedals. Whenever I see 12AX7 or 12AT7 tubes sticking out of pedal enclosures I immediately think, "that's gonna break quick." That one of the reasons I chose to go with subminis. They seem easier to protect, being so tiny. I'll be using JAN 6948s, guided missle tubes, so yeah, they should be a bit tougher than your average HIFI tube
Also, pedal builders seem to ignore these tubes as a resource, so what better gimmick to have
I'm a bit wary of kicking things in a pedal to 200V. I always find electrocuting customers is a bad business model lol. I was thinking of using a small voltage converter to supply ths heater(s) with 60V to maybe as high as 90V from a 12V or 18V wall wart.
Your last paragraph seems to suggest just taking a basic 12AX7 circuit and changing the tube to a JAN 6948. I must be reading that wrong, because in my experience things are never that simple.
Lastly, I'm assuming since I'm using such low voltages, the standard 1/4W metal film resistors I use in my pedals would be sufficient?
Cheers
Steve
