Does anyone know an easy way to tell the solid state Princeton 65 from the tube Princeton 65 with out opening up the back?

If you gave to open the back, my guess it's solid state. Tubes need ventilation.

It's easy to tell from the front, even 25 feet away. The '65 Princeton Reverb RI has 6 knobs, 2 jacks (input 1 and input 2) on the front, and says "Princeton Reverb" in big letters. The ss Princeton 65 has 9 knobs, 4 jacks (a single input on the left, on the right are preamp send, power amp in, and a footswitch jack), and the logo says "Princeton 65". (The ss Princeton 65 DSP has 10 knobs.) The ss P65's also have a white square pushbutton on the front for channel selection.

Somewhat more subtle, the knobs are different (a little smaller on the ss models), and on the ss models the knobs are closer to the bottom edge of the control panel (on the tube models they're centered top-to-bottom).

Looking from the back you don't need to open anything up on either to see the difference. The ss P65's have a single transformer with only the silver rectangular cover sticking out of the rear chassis panel. The tube '65 Princetons have two transformers entirely exposed, hanging down from the bottom of the chassis. And the tube models have tubes hanging down (the preamp tubes are covered by silver cylindrical covers, the power and rectifier tubes are either exposed or covered by a silver metal cage).

Thanks for the info. I was asking about the front view because I saw one in a pawn shop for 139.00 and was hoping it may have been a tube model that was mistakenly being sold too cheap. I wanted figure out the type of amp without drawing too much attention to it, in case is was about to make the snag of a lifetime. Pretty sure it was a SS model from the great front end description posted. thanks for the info.

My thoughts exactly. I was hoping they made a BIG mistake and did not want to show too much interest and clue them in just in case.
No such luck.
