Just received a Sanyo 2050 Receiver

Weight?

How many kg?
Thx

Sorry, I don't have Pics yet, but it really sounds good! The JBL2600s (connected to Speakers B) did'nt have quite all the bass I had hoped, but I also connected some KLH 120 as Speakers A, and using both, the unit was very impressive. It has a large volume control in the middle that goes from 0 - 100. I never got it past 10 as it was too loud. Everything seems to work OK on this Sanyo 2050, but there are a few things that I noticed that seem a little unusual. To tune the FM, I found that it was better to turn off the FM Stereo, and then to tune in the station using the tuning meter. The Signal Strength meter seems to only work on some really loud and obnoxious AM stations. Once an FM station was tuned in though, after a few seconds, the green quartz-lock light would come on indicating that the station was locked, and then I switched it back to FM stereo. This was all using the built-in little FM tube Antennae on the rear of the unit. All of the function lights seem to work, but the radio dial is not lit, not even the selector needle. I've replaced light fuses on an old Superscope receiver in earlier days, but don't know if this one has lights that need to be replaced, or if that is just the way they were made. The Power meters, Signal Strength, and Tuning meters are all lit. Did I mention it sounds great! Even the wife and cats liked it! I've read some online info (what little I could find that suggest that this receiver is 50 WPC. That sounds about right. I'll get some pics and post later.

Darlington Power Packs

Cut off about 5 feet of some old 300 Ohm Antenna wire, and connected, and it works much better. This morning, I took off the covers to see If I could get the radio dial to light. At first, I could find no lights for the dial, but soon found some on the sides of the dial. I looked for blown fuses, but could not find any. I even removed the bottom. I then decided to check the voltages applied to the bulbs, and when I was checking the one on the left side, they all of a sudden came on. I re-inserted the lights to the sides, and they immediately went out again. I tried jumpering around one of the bulbs, and then the right hand bulb worked as they are wired in series. It looked ok, so I went ahead ans soldered a small jumper around the non-working bulb, until I can find a replacement (the bulb will have to be desoldered anyway).

Nice receiver. Good luck with it. I like just about any receiver that uses the 10-pin Darlington Power Packs. If they fail, they are easy to replace and it is nice to know that when you replace a Darlington Power Pack, you're replacing an IC with all of the driver transistors, the darlington configured output transistors, and maybe some diodes, and resistors too. So that reduces the number of discrete transistors that can be at fault in ur receiver. So replacing one power pack totally rejuvenates one whole channel - except for the power supply and the preamp.

Nice heatsink on ur Powerpacks, so they should live a long life In that Sanyo receiver. :yes:

Replacing power packs is easy, finding good ones to replace them with is a whole different subject, they haven't been made in years. Fleabay/Chinese power packs don't count.
