    Modern substitute for Yamaha R-2000

    Is there a modern receiver with WiFi and transmitting abilities that is comparable in sound quality (and possibly looks) to a vintage Yamaha R-2000 (or a CR-2040)? I do have a Wiim Pro Plus that I currently use as a DAC and for streaming - but I’d like to add the ability to wirelessly (ideally...

    How do you tell what is most important when substituting transistors?

    A constant topic - transistor substitution. I needed a sub for a 2sc1222, and as the dates on the threads change, so do the answers. Some is due to obsolescence, of course, but it is changes due to the understanding of how the transistor is applied in the circuit that seem the most important -...

    SAE 2200 transistor replacement

    Hello from Oregon coast. I am replacing some transistors in my SAE 2200. The same ones that always blow. The drivers and emitter resistor between them. Last time I did this was a long time ago. I used 2sa1011 for (sae# 11-0150) and 2sc2238 (Y)for (sae# 11-0151). That channel is still good. But I...
