I don't know that I'd be overly concerned with caps unless they are in the regulator circuit that supplies dc voltage to the final. I suspect that the regulator/modulator pass transistor is breaking down when heated, or something in that circuit. If it were the bias regulator diodes, the power wouldn't rise that much. --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com). Version: 6.0.740 / Virus Database: 494 - Release Date: 8/16/2004 I only stated the Obvious caps because it may cause issues with the 8v Regulator, which he seemed to think he had a temp problem with. If the caps were leaky or shorted it could stress the regulator and it could cause issues in other areas. Another thing to remember is the Final chain is always connected to power, even with the radio OFF. So he may want to Unplug the radio when its gonna be sittng in the hot sun for a while. Rogerbird |

Never had this problem again.Think it is just too hot. Probably shouldnt be operating the radio at that temp anyway. Maybe I should consider running an air conditioner duct to the radio. :-] -Dr.X |
