Great condition, rated at 10 watts each for integrated music or 25 watts each for a guitar amplifier.

3300 ohms is the perfect primary for a pair of EL34s and I have the perfect 3 way

switches for the 4,8,16 secondary’s.

These also have screen taps, which you may or may not use. Either way is fine.

I believe Triad made these as replacements for Williamson amplifiers.

In addition to being great for use with EL34, it also is perfect for the 6A5g, 6A3, 2A3 and 6B4G.

It may be suitable for others as well, like four 6v6s etc.
