I'm thinking another oldie but goodie ? Face place and switch was caved in and damaged in shipping , was able to change the switch and bend things around and get it going. Was told sounded good on SSB (AB?) and AM ..........single mosfet driven Grant LT , 1 to 20 on AM and 20 on SSB . (no clips) The 4 gears on the amp work well (lots of swing in all gears) I'll say 180 talking pep watts AM/SSB. Was looking for any history on this 5 pound little beast (heat sink galore) the receive amp is out (kind of working in reverse) Just to guess , Could it be a small transistor needing changed ? (there's only 3 of those) Maybe around the one relay ? Thanks much . Switch
