Got this used on ebay a few months ago. It sounds very good for the price. Comes with 6 extra tubes, 5670 to 6922 adapter, a nice carrying case for the tubes, the amp, the power adapter, and the manual. I don't have the original box.

The tubes are:

1x stock GE 6BZ7
2x Electro-Harmonix 6922EH
2x GE JAN 5670W
2x Russian 6N3P (2C51 equivalent)

NOTE: Be sure to use the 5670W and 6N3P tubes with the adapter!

I'm looking for $150 USD shipped and PayPal'd. Please let me know if you have any questions!
