its a typical pioneer of the time period. solid and beutiful to look at. there are likely many equalizers that equal or surpass this units abilities but this one wont disapoint you unless you want flashing lights or maybe a questionable pink noise generator. not outstanding but very solid.

Can anyone give me the number or a compatible bulb for the pilot lamp on the SG-9500? It's a very small lamp with two leads coming right out of it. Appears to operate on a low voltage of 6 or 8 volts.
