Marshall JTM 45/100 40th Anniversary Limited Edition Hand Wired #180/250

Motivated to sell - make an offer!
New JJs in pre and power-amp stage and biased by reputable Los Angeles guitar tech. Only 250 made. This is #180. Comes with certificate of authenticity, signed by Jim Marshall himself, original packaging, speaker cables, power cable, covers, original tubes, and all original materials seen in the photos.

This is for the complete stack.  The head and cabs are available separately and as a "bundle".

It looks and sounds great. This stack has been meticulously cared for, played, but never toured, only studio use.  It was bought new and is being sold by the original owner.  These 250 are the absolute best historical accuracy, build quality, and finish of the full stack. The JH100 and 1959HW are not the same machine.  Arguably the best amp of all time.  Monterey Pop!

Shipping cost will vary based on your location. Local pickup in Los Angeles is preferred.  We can have it delivered to you if you'd like.


From Marshall:

The JTM45/100 Limited Edition run of 250 is an all-valve, 100
Watt head and two 4x12 cabinet setup. It uses two 50 Watt output
transformers in its power section, just like the original did in 1965.
It was the very first appearance of what has now come to be known as the
100 Watt ‘stack.’

Marshall’s goal for this handwired re-issue is both obvious and simple - to make it as identical to the late 1965 made originals as possible. To this end the circuit, cosmetics, construction, sound and all-important dynamic characteristics all have to be 100% correct - and they are. Marshall went to incredible lengths to achieve maximum authenticity and are delighted to report that their suppliers were equally as exacting in their tasks.

As you can see from its front panel layout, the JTM45/100 is a
traditionally straightforward amplifier. Its two channels - High Treble
and Normal - each have two inputs (High and Low sensitivity) and
separate Loudness (volume) controls. Both channels share the amplifiers,
the JTM45/100 performs at its very best when turned up to deliver your
personally preferred dynamic range. Due to its power rating and
astonishing projection, it can be a formidable live amplifier in even
the largest of venues. A truth bore out by its impressive history
time-and-time again.

The JTM45/100’s organic, vibrant, sweetly distorted, harmonically rich and thick musical tone emanates from its power valves being driven into a dual 50 watt output stage. When ‘cranked,’ the JTM45/100 produces its own unique roar with an inspiring ‘punch you in the chest’ clout. It reacts superbly to the guitar’s volume control/player feel combination and, not surprisingly, responds exceedingly well to picking dynamics too. From ‘in-your-face’ when you play with unbridled aggression to subtle ‘in your ear’ blues caresses when you pull back and turn down....just like the celebrated
masters of the day.

The speaker cabinets for the Anniversary Stack, 812T40 AND 812B40, have been designed to recreate the majestic look of the original 8x12s when stacked. Marshall could, of course, have replicated the 8x12 but in consideration to your back (and your roadies!) has decided that dividing it into two 4x12s was much more sensible! Just like the original 8x12, both cabs are loaded with Celestion’s highly celebrated T652 Alnico Speakers. The angled top cabinet also features a semi-open back, just like the genuine 8x12 reference we took our dimensions from.

JTM45/100 LIMITED EDITION TECHNICAL INFORMATION:

Components:
Wherever and whenever possible, Marshall has gone back to the orginal
manufacturers for all components to maintain the highest quality and to
ensure maximum authenticity.

Valve compliment:
Three ECC83s (12AX7s) in the pre-amp and a quartet of KT66* power valves
working in push-pull. All valves are of the highest quality available
and are subjected to Marshall's usual meticulous grading and testing
processes.

*KT66: these output valves were
standard issue on mid sixties Marshall Amplifiers yielding a fat, round
tone that has a distinctly vintage flavour.

The way the three ECC83s in the pre-amp are utilized is as follows-
V1
is the pre-amp gain stage for the High Treble and Normal channels. Each
half of the valve (the ECC83 is a dual-triode which means it is
literally two triode valves in one) acts as a dedicated gain/input
buffer stage for each channel.

V2 is common to
both channels which are passively summed at the input of this valve. The
first half of V2 acts as a second gain stage, which boosts the signal
further and directly drives the second half of the valve which is
configured as a cathode follower - a unity voltage gain device which
acts as a high input impedance buffer, providing a low output impedance
to drive the pre-amp’s passive tone network.

V3
is the amplifier’s phase invertor and sits at the very end of the
pre-amp section’s tone circuit. V3 divides its input signal into two
separate output signals that are inverted with respect to each other -
hence, the name ‘phase invertor’ (a.k.a. ‘phase splitter’). The two
resulting signals are then fed to the push-pull power output stage of
the amplifier.
