Does anyone have info on a Magic Eye by Radio Record type AC/TVL which is on a Ct8 base? I can find no mention of it anywhere. regards,Les.

Could it be like/equivalent to a TV4 (also Ct8 base)?

Thank you,Turretslug. The TV4 had occurred to me,I did wonder if the heater might be 6.3 volt working. I dont have a TV4 card/s for my HSVT (if there was such a thing) so maybe I'll wire a test rig and see what the result is. The electrodes seem very similar to the TV4. I have a Mullard EM4 but as it is painted red you can't see much of the internals. Les.
