Can anyone help with some specs for these tubes? I thought I had
comprehensive references but these have me stumped :(
1. tube marked 6RA3 Made in Japan, in a CEI box (red & white) marked
6R-A3. Appears to be a tetrode, plate looks about 5 to 10 watts, cathode
looks robust (sim. to 5763)
2. tube marked VU508 & 10E/520, glass high vacuum rectifier, anode top
cap, oxide coated fils, European 4 pin base
any help appreciated
cheers Nigel VK3ZNQ AMI# 1040
