THD Bi-valve 30 hotplate amp / attenuator - $800 (San Mateo)

For sale is my THD hotplate Bi-Valve 30 tube amp/attenuator.
I bought this new a looong time ago… and then never used it - it was in climate-controlled storage since then.
In perfect technical and cosmetic condition.
Comes in carrying back with carrying strap (although I would recommend not using that, as the unit is heavy).
The admin stuff - yes, it is available - not interested in trades - Cash or Zelle only - lowballers and answers without a phone number to text will be ignored Thank you PS: https://www.
