Introducing DIY low frequency amplifier, ancient tube drived on a famous circuitry.
The Western 349As are used for power tube, pentode but incredibly with no negative feed back. According to my experiences on pentode only these 349A required no feed back with marvelous, clear and transparent sound in high and middle ranges. Delay timer is for ancient tube heater protections. Drivers are Russian recent 6SN7 SRPP circuitry as usual.
Photo shows inside of the trial case, an amateur's wiring technology but the soldering were certainly done.
