Hi, I'm interested in building a simple tube stereo headphone amp, I found a circuit but have a few questions.
Link to circuit (Site is in Japanese, but schematic is perfectly readable)
First, the schematic calls for a 117 volt/12.6 volt transformer across what I think is the output, I can only find a 115 volt/12.6 volt 2.5 amp transformer. Will this work? Another question is about the numbering of tube pins on the 12AU7A, there's two sets of numbers. Which ones am I supposed to read? Last question is regarding the 12AU7A itself, will I regular 12AU7 work here? Thanks for your help.
Thanks in advance.
Dave
