|just waiting to see how it sounds first and will then decide if it's worth doing the cosmetics
looks to have a discrete output (fairly common in the eighties for such use even though headphone amps were not as a class of equipment) and DC coupled so I think maybe a good chance it sounds
good but measure the DC offset to be safe.
The power section looks a tad weak (cap size) for driving a dynamic headphone below 150 ohms which may be what it was designed to drive
so also check any series resistor on the output for size.You may find 100-150 ohms there and again not good for low Z cans (again though common for the time).
Finally the cosmetics-
Everyone has different taste so what I like another may find AWFUL
If you shake loose that nasty a*s wood "jacket" you may find the actual lines of the amp not too shabby.Deeper than wide works very well on a shelf along side of a Cd palyer even though looking out of place on a bench for a photo shoot.
Disregarding a replacement
for the wood cover think on what actually is visible when this amp is "in system" and that is the front panel and not much else so why I suggested painting the metalwork and then adding only
a front panel of hardwood.That is what the Rickster would do.
The Mikester ? I don't think even he knows
