The video below is from a JTM45 plus build by Tube Depot. This video was actually recommended by another JTM45 kit vendor as the build instructions. It's a good source although it is not 100% what I will be building with the TubeTown (TT) kit. You will find links in the video to their schematics and build instructions that are good. Differently: cut off JTM45 schematic (#1) before PI coupling capacitors. Get new schematic (#2) and put cutted power stage near by #2. Connect #1 schematic's coupling capacitors to PI and connect OT secondary winding in parallel with OT secondary winding in #2. And you've got JTM with dual OT. Top.

So I'm diving down the JTM45 rabbit hole. I'm trying to find a good looking schematic/layout for an original-ish JTM45 that was done with 6L6/KT66/5881 and 4 x 12AX7's. I went to MojoTone, but their schematic is for EL34's, and those are quite a bit different. I went to this website here.. Looking for clean, readable JTM45 schematic. Collapse.

Name: Hans Bos Rating: 5 Senior mechanical engineer I got the JTM45 as a retirement gift from the company I worked for. I found that the parts and components were high quality. The instructions that come with the kit are minimal. A schematic and wiring diagram comes supplied. Be sure to check website in case of any updates to wiring diagram. I did have an electrical engineer check my work. But I guess all that is moot since the JTM45's in quesiton both have screen resistors (although they look to be 470Ω, implying the use of KT66's or 6L6GC's rather than EL34's). Logged Build problems?

To understand this one, we must have a short look on the JTM45's schematic. Basically, the JTM45 is a smooth copy of the Bassman by FENDER, with a slightly different choice of tubes. Here's the rough idea: The guitar's small sound signal gets amplified by the first tube triode. The volume pot of the JTM45 follows this first stage. The signal is then amplified again and sent to the EQ. 1 Build Your Own Clone Classic Brit 45 Kit Instructions (Revision 1.0) WARNING!!! HIGH VOLTAGE!!!!

The very first Marshall amp, made back in 1962, was the JTM45. It was an instant hit and launched a whole new generation of groundbreaking guitar players. It came with a schematic of the entire circuit, and a wiring. Labeling schematic features is an easy way to add descriptive text in your schematic diagrams.

The Black Flag JTM50 is a rather rare and coveted after amplifier made by Marshal between 1966 and 1967.It was one of the transitional steps between the JTM45 amps and the plexi panel JMPs and later metal faces. During the short period of time it was produced, the JTM50 saw a few important spec changes that would be a precedent for further development of the Marshall guitar amps

I have big problems with this terrible Popping sound then I turn it on and off. Whereas a JTM45 puts out 30-35 watt at the point of breakup, these early amps put out around 70 watt at the point of breakup (and more than 100 watt at full breakup). The choke (inductor) on these early amps appears to have been the Radiospares 20 henry choke often seen on the early Marshall schematics. The Radiospares choke is different from the Drake and Dagnall chokes used later. The. Amp schematic (courtesy of Ilppo Nousiainen) DEA100 MkIV Super Amplifier.

Please find attached a simple way to modify the JTM45 with a Master Volume control. Just replace the 2 220k resistors R22 and R23 by a 250k log potmeter and wire this up according the schematic diagram. The potmeter can be located in the faceplate by removing one input socket or drill an extra hole in the rearplate When it comes to output transformers for the JTM45 amp, Mercury Magnetics offers a plethora of options beyond the stock, cloned, vintage replacement. Options available in the Axiom line of output transformers are primaries optimized for KT66/6L6/5881 tubes or EL34/KT77 tubes. Secondaries with just about any output impedance combination that one could want. Many of these custom Axiom models. Re: 1987x vs. JTM45 Let's see some more discussion here! I'm looking at converting an old PA to a JTM45, but want to be able to option it toward 1987, also. One thing I found interesting during my recent search for JTM45 schematics - I couldn't find a 2-channel normal/bright version of the JTM, like we expect from the Plexis and other NMV.

Alors certes il y'a une différence entre le JTM45 2245 de chez marshall, et le JTM45 de tornade ms par exemple, ou ce dernier a une dynamique de dingue, ou toutes les notes ressortent, ou tout est parfait, et le RI qui va être un peu plus fade. Mais bon, pour moi qui joue à un niveau amateur, je ne vois pas grande différence, et surtout, qu'est ce que je kiffe cet ampli!!!! D'autre diront. The JTM45 platform, this 4×10″ combo included, achieves that High Treble preamp stage with a bright cap of moderate value (0.0001uF a.k.a. 100pF) in the form of a high-pass filter around the channel's Volume control, and another around the 270k-ohm resistor between the Volume control and the PI. Otherwise, both channels use .022uF coupling caps for a round, full, balanced frequency.

The JTM45 (Marshall's first amplifier) was Jim's version of Leo Fender's 5F6A Tweed Bassman amplifier. The circuits were nearly identical, but the JTM45 had a beefier power supply, and when used with KT66's & a 4x12 cab, this amp had a British voice all it's own! A glassy top end with warm & creamy midrange tones makes this amp desirable for many genres of music, especially classic rock. JTM45 Model . Legendäre Amps haben mich schon immer interessiert.

Jtm45 Reissue Manual The very first Marshall amp, made back in 1962, was the JTM45. It was an instant hit and launched a whole new generation of groundbreaking guitar players. Since I can't afford a real or reissue JTM-45, I'm considering buying a kit and and a few more mods are listed in their instruction manual that I added as well. A project such as this JTM-45 reissue transformation offers. For example let's look at a standard coupling cap in the schematic below. It has a 100k plate load resistor connected to the DC power supply on one end and a 1 megaohm grid leak resistor connected to ground on the other end. The 100k to the power supply is a lower impedance than the 1 megaohm to ground so the cap's outer foil lead should be connected to the 100k plate load resistor.
