!!CAUTION!!
HIGH VOLTAGES EVEN IF UNPLUGGED!
TUBE / VALVE AMPS CAN STORE VERY LARGE
VOLTAGES! THESE VOLTAGES CAN KILL YOU!

You have to understand how to safely work inside the chassis of a tube amp. Just reading this is not enough, but here are a few tips: Never work on a amplifier that is plugged into the wall socket, always unplug it first! Stand on a rubber mat of some sort and don't work bare foot, under the influence of alcohol or any other drug, legal or not for that matter. Here is another good tip: Only probe an amp with you're right hand and with you're left hand by you're side. So if you do happen to take a high voltage shock, the the voltage will not go across you're chest!

High Voltage is stored in the electrolitic capacitors and they need to be discharged!That's what I'm doing in this pic. These are those large round can's and there usually blue or black. The discharge tool is made of 600 Volt wire with a 3-5 watt resistor of 500 to 1000 ohms. Basically you clip one side to ground then clip the other end to the Pos + side of the capacitor. Check with you're multimeter set to 600 DC volt setting and make sure the voltage has been discharged.

New Fx-Loop Kit


This is a new Item that was requested by a good reader here. He wanted to add an FX-LOOP on the JCM800 Layout seen at this site.

Note: It has not been tested yet but I am working on it.

You will need to find space to add a few extra componnents, a new pre amp tube, two jacks, two pots(send & return), and a 3" X 3" area to mount the board.

Kit will come with all parts needed for this kit, and 4 stand offs.
