Yard Sale Tandberg TR-1055

I had it's big brother. Very nice stuff indeed. Sounded a lot like a Luxman R-3045 so nice stuff indeed. Excellent build quality.

Here's a pic of my baby.

That is beautiful. :thmbsp: One thing that surprised me a bit was the relatively small size of this one. It's roughly 17.5"wide x 13" deep x 4.5" tall. I believe the next generation was slightly larger?
 
This is one of my TR-2025, fully serviced. Given to a friend, together with a TCD-310MKII.

The others I have to service yet, also a TR-1040 which is completely disassembled by the pre-owner. Power amplifier destroyed.





 
Nice receivers, guys... esp. that 2055.

To the OP on your new 1055: for sure you want to look for & replace any of the gold Frako caps. I wouldn't be surprised if the weak channel is cap-related on this model, either - but start by making sure the switches hiding under the lower control panel are thoroughly deox'd. There's one at the far right that is particularly prone to causing dropouts or lost signal (recollection from the last 1040 I worked on, which is very close to the 1055).

Watch out on the lamps. The ones behind the meters look just like the dial lamps, but they're lower wattage... presumably to ensure the meters don't get damaged by heat over time. The originals were frosted E10 T-3.25 types but there's about 100mA difference in consumption between the dial lamps and the meter lamps.

Speaking of the meters, be very careful with them if they're still working. These are very fragile in my experience, almost every one I've run into has had broken tuning meters in it.

I can send you some lamps if you need them; I stock both types as well as the FM stereo lamp and the little grain of rice lamps for the function indicators and dial indicator. I frost the dial/meter lamps myself to keep the look & feel same as the originals.

Wow, that is beautiful! Your friend is lucky.
 
He needs to get that nasty Frako cap out of there before it wrecks all that pretty, though. You can see it peeking out at the lower left from under the tuning mechanism crossbar. 1000uF/63V axial, part of the +25V regulated front end power supply. Replace it with a nice Vishay and adjust the voltage, and it's good to go.

John, thanks very much for the advice. It will probably be next weekend until I can give it a thorough Deoxit bath. A full recap (which would be done by a tech; I don't have those skills) probably isn't in the cards due to the cost, but I will plan on having a tech replace the gold Frako caps in addition to anything else that needs to be done, once I take it in. It will interesting to see if deoxing cures the slightly weak right channel, or if that turns out to be cap-related. The good news is, after spending a good bit of time listening to a few FM stations of various strength on the 1055 this weekend, the meters are working, and working accurately. The tuner on it is a joy to listen to. Thanks for the lamp info as well; I may take you up on it as the project moves along. I always wanted one of these, and now I've got one! I've been selling off some stuff, but when I saw this I had to buy it.

That TR-2055 is sweet lookin'!
It appears though that it has FM only no AM?

Which the lable on the unit clearly shows FM Stereo Receiver.

But yet the radio dial scale appears to have the scale for AM as well?
 
The lower dial marking is just numbers, 0-100 as seen in the closeup of that TR 2025. The 2075/2075 MkII would have AM frequency markings there.

TR 2025 power transformer rewiring for 220 volt operation

Does anyone know if the power transformer could be re-wired for 220 volt operation. Based on the pins on the transformer, it looks like it could be wired.
 
Wow, that looks great! It's funny how the "modern" look has come back. That would look cool sitting on a credenza or a built-in bookshelf.
 
AstroZon, you're commenting on a thread that was a year old before joosof woke it from its slumbers... though I agree with you, they do look great and in more places than just bookshelves or credenzas. :thmbsp:

josoof, welcome to AK... should drop by the Introductions forum and say hello to the group when you get a chance.

As a rule, you'll get better responses to questions about other gear (this thread originated as a discussion of a TR 1055 found at a yard sale) if you start a new thread, rather than tacking your question onto the end of an old, dormant thread.

The answer however is yes; the 2025 can be configured for 120V/220V/240V by changing the wiring configuration on the primary side of the power transformer. To the best of my knowledge, they are all multi-voltage units though there are two transformer versions covered in the service manual.
