Strange - mine in the OMNI VI+ does NOTHING to either of these types of noises no matter how you adjust the radio. I'll have whatever Bill is having...
Nope. The power switch only sends power to pilot lamps and filaments on mine. The standby switch energizes relays that apply primary power up the HV transformer. Best regards - Bry Carling
Nope the testing was done as follows: Applied 120 VAC to the secondary. Then check with AC VOLTMETER on the primaries. One showed 3.65 v and the other showed zero. The good primary reads 0.5 ohms and
Keep a spare transformer handy. They are $565.00 plus CRATING charge AND shipping from Tentec. Not sure where they get them but guess there is some mark up. The insulation gets cracked, old, dry and
Ten Tec has some very good detailed instructions on tuning in their manuals. It is quite clear. I apologize for any duplicate messages today. My iPhone was misbehaving again ! Best regards - Bry Carl
Well if you like I can scan the manual pages and schematic of my 422 Centurion. It is exactly as I described to you. HV Board has 3 relays. One is for soft start, and the other two apply 240v AC to t
81536 HV Board schematic for my centurion 422 amp just for Robb. Yes I did understand. It shows the three factory supplied relays on the board ... The ones you say don't exist.
Thanks guys, It does appear that I was partly mistaken about how the soft start circuit works with the three relays. Power is indeed applied to the transformer whenever AC Power switch is turned on a
Thank you so much. They never brought up that possibility during my calls to Tentec while troubleshooting. However the previous owner did mention to me that the QSK board had already been replaced. T
