Their built like tanks! Quality throughout & you won't need a "driver" (modulator, etc.), unless you want to replace tubes often! They kinda look like the newer Maco's in their layout, & the only "issues" I've had w/ either amp was the keying circuit. Changed to a TIP-31 trans. & "good 2 go"
I currently own 2. Both are labled "Super Scout". 1 is built using 4 ea.- 6KV6A's driving 8 ea. - 6JE6C's (all tubes are matched Sylvania's from RF Parts), & the other 1 has 4 ea. 6JE6C's driving 6 ea. - 6LF6's (all tubes are matched, tall bottle GE's). Tubes in both are NOS, hence their home in a display case! The 10 tube started life as a 4 driving 4, but was sent back to the amp builder to have bigger Xfrmrs added & sockets changed, etc., etc.
190, I'd bet you're asking because of the current auction on ebay...., his claimed wattage output of 1400 is kinda high for a 4 driving 4, but you know how wattmeters are. Plugged into a 30A service, my 12 tube Scout does 1400, & the 10 tube will do 1800. I figure my Bird43P & 55's Bird (in his shop) are pretty accurate.
Anytime I see an "unmolested" Scout for sale, I try to snatch it up! I was going to bid on the amp, but I think the ebay police killed the auction.... ,
Just my 2 cents....
