Early 70’ies YTA-100. Very rare. Combination of the PSE200A and the TS100. The PSE200A is a 2-channel preamp with on board Reverb, Tremelo and Wahwah. Including the original footswitch.
The TS100 is a powered (100 W RMS) 2×12″ speaker cabinet (32 kg!).
Some little cosmetic issues and some minor mods, but in a decent condition for an almost 45 year old.
