My cherished Yamaha CR 2040 is in need of a complete over-haul. I'm looking for something top-notch, someone that will know the unit inside-and-out and can return it to its original working splendor?
As you have a receiver that is over 30 years old, anyone who actively worked on them will either be retired or have likely archived their knowledge. I did work on them in the 80's and you will have a problem with getting a "complete overhaul". I assume you have burned out bulbs, noisy switches and controls, and other issues. The original bulb type that twisted into contacts on the board will have to be done differently. While controls can be cleaned if there circuit problems due to caps or transistors it will likely be labor intensive. Your best bet would be to find a long-time self-servicing dealer in your area but this unit is not a McIntosh so you need to lower your expectations.
Found the best place in the WORLD! This guy and his shop are one of the last great engineer run repair shops left. He receives equipment from all over the world, from customers looking for the best possible repairs of their cherished gear. I drove the 4 hours from PA to CT to get my Yamaha to his shop....great price too.
