Just got this Richter RS-22 amp yesterday and I can't turn it off! It is a 22 watt 6V6 Narrow Panel 5F6-A circuit in, obviously a 1X12. I have always drooled over the sound of the 5F6-A 4X10 Bassman and when this fell into play and I researched it I was SOLD! Same 4-input, Double Volumes, Tone Stack and Presence circuit as the original circuit. Crafted and hand wired by Gene and Sara Richter in Illinois. They make a 33 watt version as well as other Tweed amps. Incredible build, top notch! Is running a Jensen Jet Series Electric Lightning which I am really liking. Very Fender sounding speaker with alot of headroom and smooth, creamy breakup. The amp sounds amazing. Great clarity and sparkle yet thick and creamy as a Tweed should be. I play only Strats and Teles so I haven't even investigated the Bright inputs, but the Volume pots are so interactive. The Presence circuit is the true secret for me. My Telecaster through this amp is a thing to behold. The prices on Richter amps are just jaw-dropping low for the product.
