For sale is an upgraded Hafler DH-110 preamp. The following upgrades were done:
All bi-polar power supply capacitors have been replaced with greater capacitance modern units and bypassed with Wima 0.1 uf poly film caps.
All non-polar signal caps bypassed with Wima 2.2uf poly film caps.
New matched 2.2 uf poly film coupling caps in the line section.
Power supply rectifiers replaced with HER108 ultrafast 1A 1000 volt rectifiers.
All RCA input/output jacks replaced with modern nickel plated brass jacks.
All ribbon cables, pots, and switches were cleaned with Caig DeoxIT Gold D5.
Cover, knobs, end caps, and faceplate perimeter repainted.
Asking $300.00. I'll pick up the PayPal and shipping fees.
