For sale is a Hafler DH-100 Preamplifier. All switches and jacks cleaned with Caig DeoxIT D5. Back panel RCA jacks were burnished and then cleaned with Caig DeoxIT D5. Op-amps in line, tone, and phono sections upgraded to high slew rate wide bandwidth MC34082 op-amps from Motorola. Line-stage caps, output caps, and tone control caps replaced with modern tight tolerance film units. Replaced 1N4007 diodes with HER108 high efficiency units. Power supply electrolytics (pre-regulator) replaced. Asking $90.00.
Thanks,
Ron
