I took the completed amplifiers out to the garage for a smoke test.
The two pots were set roughly half way. One amp had a little more output then the other, but I am not going to get excited just yet. My 2A3's are used and are marginally matched, see what happens after I adjust the pots are properly adjusted with a DVM.
Tomorrow I will figure out how to prop the amps upside down so I can do some tweaking with the tubes in place. The 2A3 is a touch taller then the transformers.
In the garage I wired a couple of 92db speakers in series to get a mono speaker roughly 16 ohms for the trial. The source was a cell phone.
-17 is not an ideal temperature for the speakers with rubber surrounds, but what I did hear was very good!
Hopefully tomorrow I will get them into the system. I will update after I get a chance to give them a real listen.
Eventually I will make some plinth bases for them to cover up the bottom and maybe add some ventilation.
Big high five to Paul Joppa, Thanks.
