I have 2 Accutronics reverb tanks to let go.
The first is model # 4AB3C1B This is a shorter dwell.
The second is model # 4fb2a2c This came from a Hammond organ.It's a 2 spring unit.
$23 each shipped, or both shipped for $35
Both work fine, and are in great condition.
Sorry about the upside down pix!
Thanks for looking,
