Handmade point to point 300B Class A single-ended tube amp

Product functions and features:

1: The high and low voltage switch is designed to be easy to use, and the high voltage can be turned off without load during preheating.

2: Current monitoring, mainly to display 300B screen current, which is convenient to check the aging status of 300B.

3: The electronic tube seat adopts a shock-absorbing structure to prevent the electronic tube filament from being oscillated by external forces.

4: Full handmade point to point, including voltage regulator circuit.

5: 1.5 pure iron paint shell, effective anti-interference, the magnetic field generated by over-conducting transformer.
