New in da place … tests to come !
BTW, I’m looking for this kind of screws, 2 or 3 have been replaced with ugly parts …
It seems to be from 1969 if we look at Celestion cone code (see the Celestion site) :
- EB22 : 22 mai 1969
- EB7 : 7 mai 1969
(many thanks to superchouf from www.projetG5.com)
What’s the purpose of this variable resistor ?
OK, it’s time to service this baby, and this will help me a lot :
