This is my first post on headcase so please let me know if I miss anything.
I own a pair of ELS-63 whose EHT boards could do with upgrading.
I have most of the components (3KV caps and GP04 diodes, resistors etc. ) but the only component which I am unsure about is the VDR (Varistor). The schematic does not give the values.....
So, does anyone know the VDR ratings i.e. breakdown voltage, current rating etc?
The original VDR is axial and colour coded Blue-Black. The replacements are usually blue Disk Types.
If anyone knows the rating or replacement part numbers please let me know....
Thanks
