You are getting the +250V but no 12V filament voltage. Check the filament fuse, which is close to the power connector, I believe (my early TR-3 does not have it).

To: [email protected] Date: Sunday, November 22, 2009, 10:28 AM I am trying to troubleshoot a TR3 that I was recently given and am trying to restore. I have never done this before and as a result have been googling everything I can find on the Drake line. I have found many good websites, but they all seem to focus more on the TR4 and TR7 series of rigs. Does anyone have or can put together for me from your experiences in working with the TR3 a troubleshooting guide? A sort of 1-10 type thing to go through. Right now the rig (I have tried the power supply on another rig and know it works) will not power up except the OA2 does light up which I understand it normal, so that is a sign of life at least. But now what do I check next?? Bob AD5VJ _______________________________________________ Drakelist mailing list [email protected] http://mailman.zerobeat.net/mailman/listinfo/drakelist
