Completely Restored  Eico HF81 Integrated tube amplifier.

 

These amps are rated
at 14 watts per channel and feature a built in phono stage.

The amp has been
restored with the following work completed:

A complete bare
chassis restoration..chassis cleaned and rca jacks labelled at back.

New Belton  tube sockets and shields in phono/preamp section,
 and  in power/ pre-driver section and NOS sockets
for rectifier tubes.

Completely rewired
with stranded 22 guage wire.

All new power supply
capacitors,  2 30uf/500v , can cap was
replaced with a JJ 100uf dual at 500v, plus an additional 68 uf /250v under the
chassis.

 All the small caps were replaced with silver
mica, bypass caps were polypropylene,  coupling caps in the preamp section and power
amp section are all PIO K40 and all other small electrolytic caps  replaced.

 

Resistors in the  power supply rail are metal oxide , most plate
resistors are Kiwame 2 watt and all others are mix of carbon film/comp.

The original speaker
terminals and all rca jacks were replaced with binding posts for the speakers
and gold rca jacks for the inputs.

The speaker terminals
have the 4 ohm and 8 ohm taps connected to the binding posts.

The original rca jacks
were terrible in these amps, making bad contacts and having intermittent grounds.
The new rca jacks are tight and have a solid ground. This comes with a new
Heyboer extra heavy duty power transformer, which has more metal core and the
heaters can handle a few extra amps than their regular replacement version.

The Input selector  was replaced with a new 6x2 switch, and thus
all the RIAA phono equalization components have been installed under the
chassis. This improves the phono section drastically in this amp with NO HUM!!

There are 3 line
inputs now, 1 phono and 1 line out.

The mono/stereo blend
switch has been bypassed, and the on/off control on the treble shaft has been
moved to the old tape switch on the front.

quiet, with no hum, all the controls were cleaned and are quiet.
