A Quick Overview of Tube Testing…

Now I mention a number of times now of letting the equipment be the final arbitter of the tube’s merit. This is simply because some circuits are not super critical to the tube’s “measured” value, and there is no question there are some pieces of equipment that are very critical of having even acceptable tubes from the tester not being good enough for the circuit (I have a Dumont scope like the one in the “Raj Mahal” which is that way.). Conversely I have a tube radio chassis that has all 5 of it’s tubes test below the question mark, and yet reception is very strong, sound quality is as good as a typical table radio and everything works as it should.

Construction of a Guitar Amplifier Worthy of the Effort

Now to be clear- this amp was not going to be a total ripoff of their design, that was not the intent, but rather this amplifier is an Homage to their design and to see if it could be accomplished with what I had available- with a few important tweeks and differences, their design only gave a starting point. To say the least, this amplifier is a “one of a kind” largely because many of the parts I used were the only parts I had on hand. Any others I build in the future will be different- even if inspired by other amps manufactured by the big name companies. Continue reading
