    Pioneer SX525 LOUD audio Crunching/distortion noise in left channel...

    HI Everyone! I am new to this site. I have had the pleasure of owning a Pioneer SX-525 for the last several years now and has been quite a reliable low powered solid state amp. Unfortunately the left channel scared the heck out of me one day by making a horribly loud sustained crunchy...

    Technics SE-A5 with random fault (supposedly bias)

    Hi, I'm stuck on this amp. The input board has been recaped. I also changed two small electrolytics on the power stage board. Right channel works fine, and bias adjusts without trouble. Left channel will intermittently work well with stable bias once adjusted. However, when the problem happens...

    Solid State amp static.

    Hello audio karma family. I just recently purchased a acurus a125x5 intergrated amp and noticed after 2 days of listening, a sound of static coming from my right front channel speaker. I did well over 5 hours of troubleshooting with my friend Audiofreak71, eliminating my rca cables...

    Amp and Preamp for $8k?

    Alright I've posted threads before looking for some insight on what I should upgrade to but ultimately at that time I didn't have the money saved to really take anything seriously. many hrs of overtime later I've saved up some cash for something new (restoring vintage gear isn't cheap either). I...

    Any suggestions?

    I recently picked up a 1980s Sansui amp, tuner, turntable and cassette deck for pennies . I know these were made after the great days of Sansui but the turntable is fine - direct drive and sounds good. The tuner works too. the cassette deck has liquified belts and I thought initially that the...

    Yamaha AX-550 iffy led lights problem

    Hi, I'm new to this forum and hoping for some guidance. I have a Yamaha AX-550 amplifier which is overall in very good condition and I really like the noise it makes through my Yamaha NX-E100 speakers. There is just one tiny (but for me big) annoyance: the leds on the power, input and volume...

    Luxman MB3045 6550 mod different from usual ones

    Hi, I'm trying to bring a pair of MB3045 back to life. They are both equiped with Sovtek 6550 wich I will replace by NOS Sylvania. I found a few mods inside, and they seem to differ from what I read: - Around the 3x47µF/450V capacitor, I see 12K-68K-150K instead of 12K-100R-150K in the original...

    2 channe vs. AVR amps - seeking more WPC c/o Yamaha

    I have a power hungry pair of Epicure 202's (4 ohm config) driven by a RX-797 (100watts into 8 ohms) Yamaha 2 channel amp. IF I'm seeking to at least double WPC i'm seeing lots of cheap AVRs on offerup. I'm also seeing lots of down & dirty PA Yamaha amps (i.e. P2201) that will do it. The...

    Restoring and Cleaning Amplifier Internals

    I've come across a Pioneer SA-510 that was kept in the garage as an amplifier. It started "acting weird" so it was given to me. I respect the vintage tech, and want to bring this thing back to life for normal use in a cared for environment. It's got 2 problems. It is oxidized inside. Rusted on...
