This amp is
ultra rare. I have only seen it twice in almost 30 years. This sample
carries the serial number 160075, but I do not think 75 units have been
4 EZ81 rectifier tubes
are used as rectifiers and ECC83 as drivers.
The pictures show the
LS-25, the LS-15, L-15 mono amp and the LS-8 with their preamps.
