Vacuum tube mono power amplifier for telefunken broadcasters. It uses Siemens F2A11 and Telefunken's EZ12, which is contrary to the apparent unessessness, with a sounding sound and a thick, soft core. For ease of use, input terminals and speaker terminals are manufactured. ※ Although it is a 220V specification, it can be used as it is at 100V with a step-up transformer. Appearance can be aged dullness and dirt. (Satoshi Yonejima)
