I did not expect a step-by-step Heathkit style guide, but I did expect accurate and complete schematics. There were a number of errors in the diagram including a node joining the B+ to the common circuit, a potentially dangerous situation which would energize the common side of the RCA terminal with 540 volts. Additionally, no diagram for the tube filament circuit was included. Better instructions and maybe some online photos of an assembled unit would be a big help. matthewdclayton ยท Review provided by ebay.comAll Reviews
