    McIntosh MR74 Lights/Bulbs specifications??

    I recently purchased a McIntosh Mr 74 and wanted to replace the lights. I believe this unit has 7 or 8 lights? Not sure but regardless I was hoping someone could tell me which exact bulbs I should buy to get this thing glowing again? I’d greatly appreciate it! I also need the same information...

    Eric Engineering - Tuner - model 357

    Hi, I haven't found much info on this tuner. Does anyone have any schematics or Info or anything? I swapped out the few capacitors I had on hand, but when I started raising voltages in increments of 30 volts every 30 minutes on a Variac, the transformer got really hot around 60 volts. So I...

    Yamaha R700 Tuner Trouble

    Hello Guys, I'm currently working on a Yamaha R700. The power amplifier was shot, so I replaced the 3 hybrid ic modules and a couple of resistors that were burnt and I recapped the whole unit because all caps were leaking. Now that part of the receiver is working very well. Now I’m facing some...

    Tivoli Model One - Red/Blue Lights?

    Hi. I recently bought a brand new old-stock dark-walnut Tivoli Model One tuner, platinum series. The box shows a 2006 Tivoli copyright... but that's not to say the unit was made in that year - just not before. I think Tivoli may have released the platinum series on a couple of occasions...

    Contact Cleaner 'type' (on Tivoli radio)

    Hi all, I just bought an old but brand new Tivoli 'Model One' radio (platinum series - yay!). I suspect this thing is near 20 years old. Stations come in and play clearly, but... while I'm still dialing in a station, the audio output can be quite scratchy/noisy. The volume knob works...

    I have cleaned and relamped my Marantz 2220. All is working great except when I move the turner up and down the dial, at some points there seems to be some very light resistance where is sounds like the string is making binding noises. Not very loud but audible for sure. I have looked and all...

    1965 Calrad tube tuner (model 202M) signal cutting out

    Hello, all. This Calrad tuner has been working perfectly, but suddenly the sound is cutting in and out and then completely out. It usually sounds great for five or ten minutes, then it just goes silent and the signal strength meter shows no life. Most all of the tubes seem to be lit, but I was...

    Sansui Seven Tuner Power Supply

    Hello everyone, I was listening to FM on my Sansui Seven, it suddenly went mute. Upon investigation, it happened to be TR002 on the power supply board which is a 2SD330. This supplies +12v to the Tuner section. The rest of the unit works fine. Many in the forum mentioned TIP31C or TIP41C as a...

    McIntosh MR78 Replacement Bezel

    I am wondering if anyone has the demensions for the rectangular bezel that essentially frames the tunning dial area and meters on the glass faceplate of the MR78 tuner? It's held on by double sided tape. It can dry out and fall off. Mine is lost. It's the last cosmetic piece I need to restore my...

    Realistic STA-225 Two disconnected wires on underside of tuner.

    Hello all, I am servicing a Realistic STA-225 and am pretty sure I popped these two connections loose. I replaced two capacitors on the tuner board, and had to move the schmidt trigger board out of the way. I made a rookie mistake and did not take pictures before I started. Pictures included of...

    Hearing radio even with no tuner connected, Yamaha Ca810

    Just got a Yamaha CA 810 off of eBay. It's visually beautiful, nicely cleaned up by the seller. However, even with the volume all the way down, and the tuner not selected, despite there being no tuner attached anyway, I can hear the radio. It's pretty unsettling. It doesn't matter what input or...

    2230 FM exhibits annoying raspiness

    Hi, all. I found a 2230 in a nearby town for an incredible price, and it's almost perfect except for two dial lights. I'm truly astonished by the fullness of the sound into KLH Sixes, which I thought only possible with tubes. I even began thinking about selling my beloved little Magnavox...

    A Specific Question about Recapping a Vintage Tuner

    • I recently scored a Sansui Tu-207 tuner. This is the Sansui TU-217 that most of you will be more acquainted with. Of course, the 207 will be in the Japanese bandwidth. (I live in Japan.) • The tuner has not yet arrived, and I don’t know how it is working except the seller says it powers up...

    Antenna doesn't help

    I recently purchased a Denon DRA-400 receiver to use in my basement. The tuner does a fair job pulling in local stations. However, when I connect an antenna to the unit, it makes absolutely no difference. I have tried multiple antennas, but the unit seems to be ignoring the input. I have even...

    Kenwood KR-3400 - DOA?

    Hi folks, I'm brand new here and am thoroughly humbled by this forum's wealth of knowledge and kind spirit. I'm not by any means an audiophile, nor do I have a huge desire to dive very deep on fixing this unit. BUT, I do have a masochistic tendency to not throw anything away, and I really enjoy...
