AV-SP1-6 Special 6 Valve : Superb amp

I bought the amp because I wanted a single-ended 6V/66L6 tube amp.

The amp sounded fine the way I got it, but I modified it by installing it in a custom cabinet with a 12-inch speaker and swapping the 6V6 with a 5881/6L6.

I now use it with an Eminence Lil Texas and Tung Sol 6L6 tube (I've also tried 1 5881 and it would reportedly also work with a KT66). The amp has high/low inputs and runs in either triode (less power) or pentode (more power) mode. That essentially means that the amp can be used at four different volume levels to achive the slightly saturated power-amp distortion, which is what this type of amp is basically designed to deliver.

Overall a great amp with a ridiculously low price tag.

If you put in an 6L6, you'll either need to install an 8ohm speaker instead of the original 16ohm unit for the best sonic result.
