Wire colours used in building a Trainwreck.
While I was reading a post about the power supply layout, I realised that I should have posted up more information regarding the Funk built Liverpool amp I have a photo of. I have submitted all the information regarding the circuit, but omitted the wiring colours. Okay this it. The heater are green ...

Trainwrecks and Mallory caps.
I shall come up with a power supply layout that I'm happy with this year. I do know that Matt Taylor has a layout for the power supply that he has been working on. One of the reasons that I haven't come up with a layout yet is that the caps of preference in a Trainwreck are Mallorys. I'm also agains...

Love to see it.
Dear Ampdoc1 I too would love to see your circuit and PCB layout. For the record, I have nothing against using a PCB except for these two factors. Firstly, I have seen a few amps that have used PCB and when the amp had a fault, a lot of damage was caused to the PCB. In the case of a Fender amp suppl...

The unfinished work.
You both are quite correct about the power supply layout. I have looked at the power supply layout of the amp "Ginger" which I didn't like at all. I also have looked at various clone amps, and the thing which is instantly noticeable is that everyone copies the board layout, but no one copies the pow...

SoZo caps in Express and Liverpool amps?
I haven't experimented with these caps in an Express or a Liverpool clone, but according to this post on 18watt.com, perhaps these caps could work quite well in a Trainwreck clone. I should point out that I'm quite happy with the Xiron type caps that I have in the Rocket type clone. With all the tal...

The Rocket thus far.
Dear Chris I had been meaning to shoot off an email to you and Matt, but for some reason whenever I send messages to you they keep bouncing back to me. At this point in time I'm building an 18 watt (mini bluesbreaker) Marshall. I've only heard good things about them and there is so much around in th...

Chris
Did you ever go to that studio in NYC and A/B your amps against the real thing?
It's the acid test. I hope to do it one day.

Re: Anyone interested in an Amp gathering in the NY/NJ area
I hope someone with a real Express or Liverpool amp attends Chris.
I think your amps will give the real thing a run for there money, or be better!

What I've heard.
I heard that the output transformer was originally 6.6K primary with M19 steel. I have heard that the 5.2K primary also sounds very good. I'm not too sure what Doug Holt ended up with. The last time I sent him an email he told me the transformer that he liked was a transformer with a 5K primary and ...

Lovely work Chris!
Dear Chris
The Liverpool amp looks great!
One question though, what is the measurement of the lamination on the front of the amp?
I thought the lamination was the same size and the height of the chassis. Of course I could be wrong.
Yours Sincerely
Mark Abbott.

The Guru's
Dear Ross and Tube dog I think the point I didn't make is this, I don't mind working out what I think works and doesn't work in putting together an amplifier, but I do mind when someone is blowing smoke up my rear end, an example of this is of course the Express co-ax story. This is definitely an at...

Re: Approach to Harmonics
Like with everything it is the easiest to get the quick and dirty 90% of things. The last 10% often costs the most and/or takes the most time. Most people are 90%-er's. Dear Ross I do feel the 90% area is where we need the help, I feel amp layout is far more important than the colour of the wire use...

Keeping it real!
I think one thing we should do on this page is to record the levels of change incurred when building these amps. What I mean by this is what wires in the amps layout make the greatest difference in the tonal response of the amplifier. What valves work best in the amp, I have noticed that the guys at...

Re: The Rocket prototype
Dear TJ
Regretably, I have been very busy with a couple of different builds of late, not mention work.
I will have to line up my friend with the recorder soon, and lay down those tracks.
Yours Sincerly
Mark Abbott.
