That wattage sounds about right to me. I have a 2 tube amp with those tubes and it does 200 watts.
Your right about low drive. Somewhere around 2 to 4 watts deadkey and a MAX of 20 watts PEP. Some tube amps need even less.
Remember back when all those tube amps were made we did not have all the dual final radios like we do today.

Thanx for the reply Hotwire, appreciate it, i havent had many tube amps and have found very little info on that amp,i got the schematic from electronics along with the operating instructions but it didnt say much in regards to output power, i guess for an 8 tuber the tubes are working as they should, thanx again brother. |
