Mark Levinson No. 29 Solid State Dual Mono Power Amplifier 50Watts X 2
The amplifier is a dual mono design, meaning that it is essentially two separate amplifiers inside a shared metal case. Two individual transformers are inside one for each channel, providing power to three pairs of Motorola output transistors per channel. The amp has RCA and XLR inputs, and I have used them at various times over the years that I have owned them.
The item may have some signs of cosmetic wear but is fully operational and functions as intended.
I'll include MARK LEVINSON ETCHED GLASS SIGN

Prefer local pickup.
