Special package price (add for the tube set you choose)
$32.50

* - Select from these choices. The tube price is not included in the "kit" price.
** - Premium Cinch micanol sockets are available. Add $5.50 per socket.
*** - Requires the output tubes for each channel be wired in series. To make the amp switchable for 6 or 12 volt power tubes
requires a DPDT switch. I have 12 amp rated slide switches for $3.50 ea., one per channel is required

# - Can be bottom mounted, will require extra washers to mount.
## - Not insulated, use fiber/nylon washers to isolate it from the chassis if req'd.
