Sencore SC61 Waveform Analyzer - Dim display
I've had this thing for ages but have used it only rarely because the
display is so dim. As I recall, I went through the circuitry a long while ago and found no abnormal readings; leading me to suspect the CRT was the culprit. A call to Sencore today lists the price of a new tube (18G28) at $198. Ouch! Does anyone have any fixit tips for this problem on an SC61. Has anyone had success using an CRT rejuvinator on an 18G28? Other suggestions? Thank you. |

Sencore SC61 Waveform Analyzer - Dim display
You're lucky to get a knob for under $198 from Sencore.
I haven't hooked up my CRT restorer to this particular tube, so I can't say how effective -- or possible -- it may be. But I do have the schematics in case anyone has lost theirs or never had any in the first place. I'll be glad to look up part values or voltages/waveforms, etc... "Mistress" wrote in message . ..

Hello
I can't find the setup information for a 18G28. If i remember i used the universal adaptor, useing the crt schematic for proper connections. If you don't have a schematic i can send you the CRT elements and base connections. Best regards George Kirk Time Antique Radio Restorations |
