"Do we have a 240 VAc Power transformer for the "G" kit"
No - The "L" kits were designed to have dual power input. The "L"
kits use a different heater voltage and therefore the transformers are
"Are the tube sockets ceramic?"
Yes, all of our kits include ceramic sockets.
"Can someone with little or no experience assemble one of these kits?"
If you can solder and read instructions you should have no
problem. If you don't know how to solder find someone
who does and have them give you a 15 minute lesson.
The best soldering iron to use is between 25 and 40 watt,
anything bigger may damage the PC Board.
If you are color blind, just find some one to help you with the
resistor and wire colors.
"Can both the Tone Control and Preamp be used at the same time?"
No, The Tone Control has gain, so the preamp is not needed.
Problems? Check For:
1) Long leads left on the bottom of the board, causing them
to short out against each other or the chassis the
kit is put in.
2) "Cold" Solder Joints. (The solder did not flow around the
lead and the PC Board pad leaving a poor or
3) Not removing the varnish from the output transformers
4) Any modifications made to the origional design of the amp.

Caution: These amplifiers may be operated as supplied, however voltages in excess of 240 volts are present on the board and the tubes get veryhot. It is advised that the amplifier be mounted in a well-ventilated metal enclosure to reduce the potential of fire or shock. We cannot emphasize this enough and we have no control on the quality of workmanship that the purchaser / builder puts into their kit, so PLEASE be careful. And Enjoy the sound of "TUBES".
