Hi John, I just found out that the connection between the regen pot and R3 was open. I ran a wire between them and the set came alive. Thanks so much for your help. Herb

Just thinking out loud here, but what if both D2 and D3 were
installed backwards? I don't have an Ozark Patrol. I'm just
relying on Curt's observations. 72, John, AA0VE On 6/1/20 6:28 AM, Curt via groups.io

Herb No voltage on Q1 base implies short to ground in that circuit. Absent an internal B-E short, the voltage should be at least 1/2V across D2 and D3. Since you have replaced that transistor, the other possibles would be BOTH D2 & D3 shorted ( not likely ), R10 (not likely), or C4 ( possible but not likely ). Did you ever try headphones? Am at a loss. Sorry. Curt
