Is there a kit available for this model? Unit shuts down seconds after
power up. B+ 129V. All trannys seem OK. Frustrating problem - is there a quick fix? As usual any info and advice is very very appreciated. thanks - Tim |

No kit, replace the high ESR capacitors in the power supply first.
Second troubleshoot the flyback, ring test it or bring set up on an oscope with lowered b+ to the flyback. Third, check for seriously shorted tube if it uses a Zenith made crt. By the time the "Z" line came out, the serious tube problems had dimished greatly, but are still seen. David Tim Marcus wrote in message om... Is there a kit available for this model?
