this one is using 2A3. not 300B. 2A3 is max power is about 3.5 W but if using before distortion will be get 5~6 Wrms. 5 W is enough to use at home. modern 2A3 will be get 5 W rms. but not recommend to use . if you use over 96dB/m/w speaker may be feel like 80W of power. so small power amplifier need high efficiency speaker .96dB ,104 dB is good for 2A3 single ended amplifier. feel like 300B. but not 300B .2A3 is good for mid and high range . 300B single ended amplifier does not have same tone of 2A3. even more power.
I do not have any distributor any place . and no need shop show. if you can buy ten amplifier or more You can do it. can you buy 10 amplifier ??? I am making at home so I do not have any equipment for demo. so if you would like to start distributor buy more than 10 amplifier first.
