Rasberry Pi - Tube Amp


Caulk Sucker
Tube Rolling – The 503HTA supports both 12AU7( ECC82) or 6922/6DJ8 (ECC88) type tubes. Individual Anode Bias Adjustments plus selectable Series/Parallel Heater Drive insure the perfect setup for virtually any tube!  See our friends at www.tubedepot.com for some alternate options!

I would try Tung Sol 12AX7. Got those in my Jolida hybrid. Full bloom.
