cabinets/ question open back or closed

thanks for taking the time to answer

i will wait until i find a cabinet with an open back

the two amps i mentioned ive had for more than twenty yesrs, i seldom played them because i never reached any

      volume or tone, also i never tried cupping until this year

i will check the tube changes i made two years ago and compare them to the tube set up you and mark used in chronicles

      at the time, i was following suggestions and had done little research to give me any understanding

       now i feel more familiar with tube changes

also i have four great speakers sitting in a crate for the same twenty years, i didnt know they were great

             i put one in a small botique amp and it sounded great

so i will try those 4 old speakers in my amps that take 4x10 speakers

        it is possible that i will change my mind and find that i like these amps, i am hoping

i mentioned the few times i did play with those amps that i never had enough volume from the amp

   if you were to choose between putting a mic from the pa in front of the amp, or going out through a line out in the back of the amp

              do you prefer one method to the other?

              and if you were blend both the line out and the mic in front of the amp at the same time, would they be about equal, or more of the amp mic'd or more of the line out

i presume you have tried these things

as always, thank you, i know that you're busy
