    Kr-2300 suddenly only buzzing

    I'm having a stroke of bad luck, I fear. I turn on my little kr-2300 and nothing but buzzing comes out. It was working fine just yesterday. I've only had this receiver for a couple of days and apart from some cleaning, didn't do anything to it. The sound is great and much more powerfull than...

    Pulsing buzz varies speed with Volume/Bass. Any ideas?

    Kenwood KR-5600 receiver, just finished recapping Audio and Power Supply boards. After resetting bias it started making buzz/hum in a rhythmic pulse that would vary speed as either the Volume or Bass control was moved. Right channel only. Maybe some transistor oscillation? Haven't had one...

    PHILIPS GA212 - a couple of questions from someone with pretty much no technical ability whatsoever

    Hello, I have a few questions about my Philips GA212 - I've read up a number of the other threads on the site but none of them exactly scratch my itch. I got the turntable last summer - my dad had one in the 70s, and it became mine in the 90s when he ditched his turntable, though I then...

    Pro-Ject 1.3 motor vibration. Normal or not?

    Hi, guys! I am fixing a Pro-Ject 1.3 for a friend who had an accident with it and the tonearm needed to be rewired and readjusted. I haven't received the new wires so I haven't listened to it yet. The point is that I decided to test the motor and the platter to check if there was something...

    Pro-ject Debut Carbon woes, regret, and acceptance.

    My first NEW turntable - fresh out of the box - hum in left channel. Took a chance and never sent it back, figured the combined wisdom of the internets could not fail me (plus I think I recycled the box). Many rubber grommets, quarter turns of motor screws, replaced cables, swearing...

    Hum generated by CD Player

    I have a CAL DX1 CD player that generates a humming sound which comes through the speakers. The hum gets louder as I turn up the volume. This hum occurs even with the CD player unplugged, hooked up to the amplifier with RCA interconnects. If I unplug the left channel, the hum is only heard in...

    Vintage Voice of Music 1428

    Around tax time this year I purchased a Voice Of Music 1428 tube amp. All original including VOM 6BQ5, 6EU7 and 12AX7 phono tube (except for one Channel Master that was obviously replaced many years ago) The plan was to make this a boutique amp since the topology was pretty simple (albeit in a...

    In order to properly feed a pair of JBL's Ti-3000 I recently traded, I purchased the aforementioned Carver power amp only to find out two strange behaviors: A) buzzing speakers - the speakers have a permanent buzzing sound that increases when both/either left and right gain controls of the amp...

    so I have a Sansui 881. I decided to recap it earlier this summer and it had been working fine. Over the weekend, I sat down near my speakers while no music was playing and started hearing a persistent ticking/flapping sound. It's not a hum but a cyclical ticking sound. If I had to guess...

    4400 Transformer Hum

    Just curious as I am new to my 4400. It has a noticeable hum, quiet but there, coming from what seems is the main transformer and I was just wondering if someone else with a 4400 could let me know if they hear a quiet hum when it is on and not playing? Of course, when the sound is on, you...

    Another FM hum question resolved, but don't know how...

    I have a Marantz 2226b that had developed a noticeable hum, but only on FM. 75 ohm amplified and 300 ohm wire produced same results. Aux and Tape settings produced no hum. So I pulled it from the living room setup and put in my basement dwelling Harmon Kardon Citation Eleven preamp, Pioneer...

    2325 hum in both channels

    I have a 2325 with a hum in both channels. It starts 5-10 seconds after the relay engages, unless the receiver is already warm, then it starts sooner. The hum is there when the Pre Out jacks are connected to another amp. The hum goes away when I touch the receiver. The receiver is newly...

My tube-tech friend found that the 4 output tubes weren't rated for the high voltage that this thing...

I suppose it could be elsewhere in the chain (receiver for example) but any ideas about the TT? I know there is a...
