I'll start by saying that I'm a relative self-taught newbie in the electronics world. I recently bought a tube amp kit off of eBay. There were no assembly instructions included, but a very self-explanatory screen on the PCB made it easy to put together.
Power supplies are a gap in my knowledge; I usually just trust the product specs. But this fails my reasonability check, so I was hoping someone else could share their knowledge with me. According to the auction listing, "Power requirement is 60VAC ~ 70VAC 0.2A & 0 - 9VAC 1 ~ 2A."
First, I'd expect it to be an OR, not an AND for the two voltages. Second, when I try to google the power supply specs, I get overrun with results that match 60Hz...not VAC...and sifting through the results for something relevant is challenging at best.
If this isn't a type, I suspect that I may need to create SOMETHING that takes 120VAC in and uses two transformers to output 9VAC and 60VAC. If that's the case, I'd like some references to sites that have examples of "splitting" the power like that so I can research the circuit. I understand how to use a transformer to change 120VAC to X-VAC, but not sure if there are other considerations to get X-VAC and Y-VAC from a single 120VAC source.
If nothing else, it's a great time for me to start learning about power supplies. :)
