    KR-6400 cutting out

    I recently got my hand on a nice KR-6400. It has nice blue lights and theoretically a very nice tuner, however it is not working... The previous owner told me that he went somewhere to get a quote in order to fix it. He got the list of not working parts (1 fuse and 2 transistors from the main...

    Surface mount soldering repair help needed.

    I have a Weller EC2000 soldering station which has begun to misbehave. I opened the unit up and the switch shown on the left (back side visible) fell out. The switch swaps the display between set point and actual temperature. Obviously it has broken from its solder pads. It is a surface mount...

    Opinion asked. Fix or dump?

    Cambridge P-140X I've had this amplifier laying around for 25 years. Of what I can remember, it started to buzz/hum real loud. Fuses ok. By then I thought it could be the rectifier that was gone or faulty. Or PSU caps (so close to the hot transistors) Today I opened it up for the first...

    Any AK'ers or repair shops near Bangor Maine?

    Hello all, This is my first post. I received an STA-2000D that isn't quite working. The right channel always crackles and then overloads and shuts sound off completely. Tapping the volume knob effects the crackle. I've tried deoxit in the switches and control knobs. No effect. Also the FM never...

    Nakamichi Control Motor Swap Dilemma

    Here is my situation: I have a Nakamichi CR-1A tape deck. It has "The Nak Disease" (i.e. a badly-designed control motor which gets wonky and won't operate the control cams properly when the transport control buttons are pressed). I also have a Nakamichi BX-125 from a thrift shop. It works...

    Sx 990 blows fuse on one channel

    Hello, I have decided to start tackling a project, I was given an sx990 and upon testing found one channel is dead. I tried a new fuse and it blew again. I measured continuity on the output transistors, non are shorter and all read within 146-148 ohms. Both channels have the same voltage at one...

    Pioneer vsx 5600 blown outputs

    Hello, I recently required an early 90s pioneer vsx 5600 receiver. The guy I got it from said it stopped working one day and the unit did not make a second click when powering on (speaker protection relay). I know he ran like 11 speakers on this poor 5 channel receiver. Main output transistors...

    NHT crossover badly damaged; what caused this?

    Hello all, Long time lurker here; I am hopeful someone has an answer/advice for me on this. About 9 years ago, I was *given* a pair of NHT 2.9s for helping someone move. I have NO business owning these as I couldn’t afford them then and could barely afford them now used. For the at least the...

    APOC module, old B&W speakers

    Hi all, Joined up to ask you clever people for help. I was gifted a lovely pair of B&W tower speakers some time ago. Turns out the model number should really be CM1/CM2, as they appear to be two boxes stuck together. My problem is with the tweeters, which are part of the CM1 OLD unit that...

    So I bought an old Sony TCS-430 at a discounted price because it needed a new belt. Bought the recorder and the belt separately and planned to replace the belt myself. The player has arrived but I'm not sure how to properly remove the back. I removed all the screws on the back of the player and...

    Newbie needs help fixing CV LS 10 crossovers

    I got a pair of Cerwin Vega LS10 speakers from a friend when he moved away. The tweeter on one speaker, however, has stopped working. I've checked the diaphragm and it doesn't seemed blown so my understanding is the next part to replace is the appropriate capacitor in the crossover. The...
