The thermisters I ordered (from Mouser) for some old Silvertone guitar amps (they have faux standby switches) were
One ran a pair of 6L6's and the other two pairs of 6L6's.

ntc thermistor there (at the ac input). They get pretty hot but it will be at the outside so....?
I'm still trying to figure out what values I'm supposed to look for. Putting it at the high voltage
beetwen the transformer and the rectifier would lower the current demands for the device.
Still fumbling around in the dark here Any input would be appreciated
Where'd you find all of those beauties? Fleabay?Dahlberg wrote:Went on a shoppingstreak so now I have gz34's, gz33's, wz68's and
a couple of octal tube bottoms to make my own rectifiers.
•While traditional thermistors are only certified for input voltages from 85 VAC to 265 VAC,
UL-recognized MegaSurge devices are certified for single- and three-phase input voltages up to 480 VAC.
It was gz37's, sellers called "Langrex", looks solid to me.
