I have boozebuttons ksa5 in house at the moment for a slight upgrade.
It is a marvelous amplifier. However it is limited to 9.28 volts RMS and
some people will say that it does not go loud enough on he6.
Balanced however is a completely different story.
There will be a diy version soon. Stackable as balanced.
Here is a high res picture of an original modified with black gate caps.
