You never know... maybe one of the most significant contributions of your life may be the uncanny ability to clearly explain things/concepts. This is extremely valuable and I am blessed to have found your channel where I can (or attempt to) absorb as much of this knowledge as possible. With any luck, I'll be able to pass some of this knowledge along to others... all thanks to you!
Thank you so much for your kind words. Every project provides a learning or relearning experience/exercise for me. Again thank you for reaching out. All the best. Don
Don, thanks! I have been tinkering with impedance all week. That fills in one of the blanks. Tonight I just had success determining an old amps input and output impedance. I look forward the the next installment.
Hi RORadios, I know how to figure out the turns ratio, I do it basically the same way though I'm using a variac to get 1 volt on the secondary, then measure the input voltage. I can also figure out the impedance... My question if you could answer is, I know for a pair of 6V6's in push pull it is 8000 on the primary. I want to add 2 more tubes, one on each side. Would I then have to halve the primary impedance to 4000? I can't seem to locate this information. I have noticed in the RCA Receiving manual that on single ended output transformers, when using a single tube, the impedance is whatever it is for that particular tube...sometimes they show for 2 tubes (still single ended) and the impedance is roughly halved. Hope you can answer. I'm making my own amplifier, not modding an existing one, so I'm planing on purchasing a new output transformer for the added power rating, ( I know the power transformer can handle the extra current draw, just want to make sure I get the proper one. Sorry so long for such a simple question, Thanks for your time, Tom Very good video by the way, I just came across your channel and will be looking at your other video's as I'm interested in all old tube gear, Guitar amps, Radios, Test equipment etc..
