Liverpool building in progress [EU]

[erwin_ve]

Being a newbie on this side of TAG, been on Dumble side, I finally had the opportunity to do a wreck.
Last year a dutch member sold his chassis and transformer set which he got 10(?)years ago from RJ.

So it's gonna be a Liverpool with Larmar ppimv. Brad Paisley had some wonderfull tones on the "Play" album and Glen K. also has some wonderfull sounding clips with a Liverpool. I hope to get somewhere close to these tones.

To find a 1k/25w for the dropping string was a pain: mouser has them in backorder.
The 130r/25w is also on backorder but without a date for delivery.
So decided to parralel 2x 2,2k and 2x 270r to come close.

Erwin,

I've built a rocket and an Express over the past few years. The express was too much for me but I like my Rocket. I tend to use it along side my Dumble to add a little extra high end and grit.


good luck with the build. If you've built Dumbles then a trainwreck is easy

Nice start Erwin. I really like my Liverpool, but I also use an attenuator exclusively on it.

[erwin_ve]

Marcus, thanks! Followed your thread on the express, hopefully I can tweak mine to my likings. I'm really curious how it behaves IRL.

Thanks Joe, did you build per layout of tweak it?

[joeboo88]

I have mine stock except .047 coupling caps. I found it is more manageable than the Express and is really sweet sounding.
I just realized I never posted my build... oh well

Joe: changing the coupling caps, was there too much bass?

Making progress: B+ and Ppimv left.

[joeboo88]

Erwin: no that's all I had on hand, i just never got around to replacing them. I've just ordered some more stuff and will be coming next week I hope .
I will change it back and see what the differences are.

Your build is coming along nicely.

Dave built me one and it's always arguing that it's the best amp I ever played through.

I swapped one resistor to get the second stage tamed. Hard to argue with the amp. It's a great rig.

Dave’s builds are always a thing of beauty.... Lucky Miles

You should see some of the photos Dave hasn't even shared with you guys of various builds, awesome jobs on his amps.

Thats a incredible neat built!
Is the bright switch replaced by a treble cap selector? What's your preffered cap? 50 or 500pF?

[erwin_ve]

I have a question: having the Allyn Mey chassis, it has cagenuts but standard (EU)mounting screws don't' fit. What is the american size(UNC)for the cagenuts that came originally with the Allyn Mey chassis?

[M Fowler]

It's been a while since I used an Allynmey chassis either 8/32 or 10/32 threads.

[erwin_ve]

Thanks M. Fowler!

Amp is finished! Tommorow measuring and first startup.
Exciting!

[erwin_ve]

It's alive! First start up was a loud squeel. PFB instead of NFB swapping wires .

Glad I installed a PPIMV , the Liverpool is as expected very loud.

First observation is: nice clean sounds, overdrive defenitly need some volume to sound good, tried some resistor swapping after the second triode(mine is 68K. 56 k made it a little less fuzzy and gave a better transition from clean to drive).

It started to feedback very soon when the volume was set high,even without a guitar plugged in.
After chopsticking I noticed the grid of the second stage is ultra sensitive. Swapping a preamp tube didn't help, this remained the same.
Is this normal? I never had this before that a grid was that sensitive, the whole wire coming from the pot is basically a mechanical feedback antenna.
