In Reply to: PCC88 heater voltage is 7,6 volt, not 7. posted by iodemus on March 10, 2015 at 13:41:07:
The heater is rated for series string (rather than parallel) operation so is usually referred to as a 300mA type , hence the 'P' prefix . I do not think using at 6.3V is a good idea . I once built a clone of Allen Wright's PP1C , this could take E88CC or PCC88 . It used DC heaters with an LM317 current source set to 300mA .
