    Marantz 4140. Hard Clipping/Chirping at near max output, but only in 2x Channel bridge mode.

    I have had this wonderful old amplfiier for around 8 years. I got it completely factory, and somebody shorted out the lamp circuit. Easy fix luckily!! Worked great after clearing the short.

    Little doubt about Marantz 2250B

    Bridging a Hafler DH-220

    Hey folks ... I recently picked up a couple of Hafler DH-220s to play with. I was looking at the manual for the DH-222 bridging kit, which seems absurdly simple. It got me to wondering if it's feasible to bridge this amp using an external apparatus. Initial internet searches have turned up...
