Re: C'mon..yor first tube amp?
First amp I ever played through for several years wasn't strictly mine - but it lived at my house and I loved it to pieces so it has to count - was a '65 JTM45 Mk.II (ali chassis, ali panel - pre plexi) sitting on an angle-fronted 4x12 Celestion loaded cab Model 1960, also dating from '65. (It had Alnico magnets, so I am guessing they were early G12's).
When it went away, I pined for years, chasing the sound through a lot of amps, many of which came close, many more of which didn't. After over thirty years of looking/listening I lucked on a 6G6-A Bassman head which just sings into my 4x12 Fane/Goodmans cab. So I have gone full circle plus a bit. First amps are like first lovers.
