    Marantz 2245 traded for Eico ST-40 a fair trade?

    I received a call from a friend in Ottawa, Canada, who asked me what I thought about the subject line. He has a small collection of audio gear, and is thinking about swapping his Marantz 2245 in excellent condition, for an Eico ST-40, which looks to be in good shape. He likes both SS and hollow...

    Optonica 5605, not 5606

    Hey all! About 10 years ago a friend of mine gave me an Optonica 5605 receiver. I have used it off and on the past 10 years, and it has worked ok and sounded ok. I have always tinkered with things and I started to do some restoration projects a few years back so I'm not a complete noob to all...

    TX-4500 MKII Value?

    I have an Onkyo TX-4500 MKII receiver that's been recently serviced, and is fully functioning. Aside from one little nick on the top edge of the stainless faceplate, the reciever is basically in mint condition. What's a ballpark value of the receiver?

    SX-980 Value?

    I have a Pioneer SX-980 that has been recently serviced. Everything is fully functioning, all lamps light up, etc. The receiver has negligible cosmetic damage, specifically a small nick in the wood cabinet and some little marks on the top of the metal faceplate. All of the faceplate lettering is...

    Dynaco SCA-80Q distortion on one side

    I have had this amp a while and decided to eliminate the hum by replacing the C9 and the C11, which I have completed. All the voltages are within specs. No more hum, great! However, I am getting distortion on one side which may have been there before I started the upgrade (perhaps I didn't...

    Marantz RS-2252...Why doesn't it exist online

    In a nearby second hand shop, there is a Marantz model no. rs2252 for sale $250...I've looked in the deepest crevices of the internet only to find nothing on this "rs" series of marantz receivers. Below is a picture. Does anyone know when this came out? Is it a good receiver? I imagine if it...

    IC Power Amp and Voltage Amp Question- Sansui R-99Z

    I'm currently working on a Sansui R-99Z that has some real issues. As soon as it powers on a faint, crackly signal comes out the left speaker but quickly (5 seconds or so) fizzles and goes completely quiet. This is a later model Sansui, and the power amp is completely contained in an STK2139 IC...

    Sony STR 7065A (Dead Switch?)

    I just recently picked up a Sony STR 7065A in immaculate condition. I was testing it at the sellers house and proceeded to flip the power switch. I noticed, what I describe as a glitchy start up - with the lamps flickering, fading in and out ever so slightly while the signal to the speakers was...

    Questions for Fisher Rc-80b

    Hi, I've got a Fisher Rc-80 with the left VU meter pegged and high-pitched noise coming from the speakers. I'm convinced it's the rcrd\play switch assembly, but I'm not sure what I need to clean. I have spent an hour looking at the interior, but I'm not certain what exactly needs cleaned...

    Zenith A589 Solid State

    Hi Everyone! I'm new to the website and was referred from Reddit. I am really excited to start the hobby (eventually probably an addiction) of listening to Vinyl and collecting it. That being said I am looking for my first set up and came across a Zenith A589 solid state on Craigslist. I...

    Noob Tube Question (seriously)

    I have always been confused by something. Well, many things but this one applies to stereo. I lived through the transition of tube to solid state, albeit young. Now that I have rediscovered my audio soul, I find myself wondering yet again about the same, unanswered question. When you think of...

    VINTAGE PHONO STAGE - RIAA

    Attached is a photo of two phono stages from early solid state integrated amplifiers. Without revealing the brand and model (and the assumptions of 'house sound') do the schematics allude to a particular tonality? Since I am not an electrical engineer it's difficult for me to decipher topology...
