| Re: CRT long warmup time? |

From: john_crane_59@yahoo.com As it turns out the caps are excellent and the voltages rock steady. Almost unbelievable for a 50 year old device (an HP-9100B). The 24V supply was for some reason at 31V. I tweaked it down with an adjustment resistor on the cards, and the CRT came up in 12 seconds. Manual says within 20 secs - so it seems fine. Thanks! -John --- SoupGate-Win32 v1.05 * Origin: you cannot sedate... all the things you hate (1:229/2) |
