Maintained! *When using balanced input, number 2 is HOT. The output transformers of this model come with TRIAD S-142A as a pair. Small tube amplifiers for commercial use in the 1950s. The sound skips very well, and the sound is fast and dry with lots of sharp sounds. This is an amplifier you want to enjoy with high efficiency speakers such as Klipsch and Altec. There is a slight feeling of use depending on the age.
