July 1, 2010 Koch guitar amplifiers
The Classic SE series guitar amps are now shipping with two types of output tubes.
   Both versions of the Koch Classic SE (single ended) series Class "A" amplifiers are now shipping with two types of output power tubes. The SE 6W is shipping with EL84 and 6V6 power tubes. This amp has both types of sockets to accomodate either tube (use only ONE power tube at a time!).
   The SE 12W comes with EL34 and 6L6 power tubes. Furthermore it can also use a 5881 (user supplied) power tube as well. All three of these tubes use the same tube socket. Since both these amps are class "A" tube amps there is no need to re-bias them. Talk about verstility of tone; it's like having three amps in one!
