I picked up a really nice condition RA103 and on checking the CRT the filament is open.
Tried resoldering the lead wires with no luck. From what I have read it would seem the original CRT is a little hard to find so what have you fellow RA103 owners used for a replacement and what changes if any were needed?
Also if anyone has a spare they are willing to part please let me know.
Thanks
