This 1951 metal lunchbox PA head is possessed; or, possesses early tweed baseman, (dressed up for the square dance)“style” cleans & some loud headroom till noon, minus the low gain inputs fender often used until 1959. It’s been owned by & rebuilt by guitarists. It’s a post war pre hi-fi. Ready for decades of viability, This hand built PA, will deliver the goods; vocals & many instruments would work here. Harmonica players recommend them. Keyboards, & pedals. 2x 1/4 inch high impedance inputs. 105 db gain at input. Interactive channel volume & treble tone control. A heathy amount of negative feedback. 8 & 16 ohms output. A 4 ohm tap exists. Phono input could become a Bluetooth / auxiliary in, is possible mod. Single wide range treble tone control, FR. 75- 10,00 cycles w/ in +0 db, - 3 db. 15 of the loudest watts, from the get go, that I’ve ever heard from any amp. It’s Locally notorious as such! Factory advertised at 15 usable watts, l it’s probably closer to 25. It has seen a near complete recap from the original two prong & death cap. Owned & serviced by the local music store’s in house Tech team!! Some more advertising from the company brochure online. 19 lbs. 1 6J5, 2 65C7, 2 6L6G, 1 5Y3G. Fixed bias. 50 watt OT. Glacier grey over copper plate housing. Lots of hand wired bells & whistles. I am second owner since re-build, @2023. I have the similarly rebuilt Au-33 model & have been very interested to learn more about these platforms! I have a 12” 8 ohm 50 watt Eminence C Rex hemp speaker inside of a re- purposed cab. Combine the two for a total of $380. It seems to be a safe way to play at a lower volume setting. It will be loud, but within amps 15 “useable” watts zone. Lol, if raising volume anywhere above 3 to near noon, a better match may look like an 80-120 watt 2/12” or 4/12” speaker cab set up with this beastly loud & dynamic Stromberg Carlson amp. Speaker cable included with amp. I’d meet on Wasatch front for the right buyer!
