Warnings – Dos and Don’ts

– Always use, and fully tighten, the head clamp to the trolley so the head doesn’t slide off.

– Always plug in the speaker cable at each end before plugging in AC power cord.

– Never turn on any tube Amp unless the speaker cable is hooked up; If you don’t, you’ll blow the
output section of the AMP. (This includes combos too.)

– To unplug the speaker cable, slide the blue release, on the XLR connector, away from you.

– Don’t pick up the speaker cabinet by the top of the trolley. (The chrome stand) The trolley is
designed to come apart just above the hand nuts.

– To remove trolley:

1 – Remove Amp Head, and loosen the trolley’s hand nuts a little.

2 – Pull up on one side of trolley, and pull that side along the bottom half
with the top half down even to where it was, but along side.

3 – Pull up on the other side to remove top half of trolley.

4 – Put speaker cabinet on chair, and remove hand nuts and remove lower trolleys.
When reassembling, always put the brown face of the large washers, inside the hand
nuts, towards the speaker cabinet.

WARNING READ CAREFULLY!!!!
Older electrical equipment often has a HOT chassis with no modern AC Power plug. This means
that it’s possible to plug in the amp the wrong way and touch another electrical device, like your
PA system, and get a belt of 110 Volts AC. I did this in the old days and saw blue lights before I
passed out! After that, I always held the guitar strings with one hand, wet my finger a little, and
then quickly taped the mike, or other equipment. Now days I use a volt meter.

The new power cords, with one prong larger then the other, prevents this.
Your Amp has the original power cord; I put a white sticker on one side;
always plug in the amp with the sticker UP as in the picture to the left. Also,
always keep the polarity (Line Reverse) switch to the LEFT as shown below.
If the power cord is replaced with a new one, the Line Reverse switch should
have the unused lead cut off from the switch.

WARNING: Only a qualified technician should work on tube amps. The big can
capacitor C-26, see page 3, is actually three Caps in one: C-26A = 270 Volts

DC, C26B = 240 Volts DC, and C26C = 150 Volts DC. With the Amp off these
caps stay charged which means that if you touch the terminals of C26 your guitar playen days are
over. Note that these terminals run to every tube socket, and else ware, so you could get
electrocuted there too. The first thing a tech does before working on an amp is to discharge these
capacitors through a high power resistor, and then shunt all C26 terminals to ground; these pesky
little devils have a way of recharging, memory, and still get ya.

ALWAYS KEEP LINE SWITCH SW-2 TO THE LEFT AS SHOWN
