Re: VVR2 into 1960s AC15 build

Still not working. Can you confirm which leg of the EZ81 rectifier should connect to the right leg of the switch/pot? I have it on pin 3. I made a fresh VVR with new parts just to be sure and i have other amps i fitted the VVR to a few years back, but the difference here is that i have never done it...

Re: VVR2 into 1960s AC15 build

Thank you. I'll go and try that now. Really appreciate it. I'll let you know if it works out.

Re: VVR2 into 1960s AC15 build

Sorry about that. Here are some pictures of the schematic i used to build the amp. including layout. I don't have digital copies of them, just printed copies, so i took pictures with my phone. I actually made an attempt at the VVR today and it didn't work. I connected to C41 for the plates of the EL...

Dream tone

Does anyone know how to get the guitar tone (other than obtain his fingers) of Ry Cooder’s Boomer’s Story, on the album of same name? I have two dream tones, this one and Willie Johnson from Howlin’ Wolf band.

I’d really appreciate advice on this.

Liverpool to Rocket?

I built a Liverpool about 8 years ago but it’s never really had much gain/crunch, even added a VVR2 which didn’t produce much gain at lower volume. I’m thinking of reworking the Liverpool to a Rocket. Would the transformers be the same and do you think this would pride a crunchier amp. I have always...

VVR2 into 1960s AC15 build

Has anyone here put a VVR2 into an AC15 (trem/vib 1960s schematic)? Just need to get it confirmed that I tap into C41 and pin 3 of EZ81.

Re: Rocket with switchable ef86?

I think i will use this to convert my Liverpool to a Rocket with EF86. Thanks Do you have any videos or sound files of the tone?

Re: Snap, crackle n pop in a Liverpool

Thanks. I'll try that out

I do have a scope, just got it recently. Don't know how to use it yet though.

Snap, crackle n pop in a Liverpool

My TW Livrpool clone has developed a snap, crackle, pop, high pitch whistling. I think it might be a bad orange drop cap, but how do i locate where a bad cap is? I've changed all tubes and re-soldered all joints on the board.

Re: My first new build AC15

I'll have to come back on that. I find all of the schematics hard to make out voltages on. The circuit boards are out at the moment but I'll do some voltage tests for those key places when it's back together.

Re: My first new build AC15

Tell you the truth, the one I'm working from is the 1961 version from Stephen's book.

Re: My first new build AC15

Here is the schematic. Interesting that you should mention that about leaking coupling caps. I've decided to take out the NOS caps, I think it's asking for trouble unless they are properly tested - which I don't do other than of a capacitance test. There is 324volts leaving the rectifier. I'll do an...

Re: My first new build AC15

I'd really appreciate it if you'd take a look at my voltages and let me know what you think. I can't find anything to compare against. One channel is low volume, lots of hum but i think that is lead dress, Vib/Trem not working, but shouldn't be too hard to fix. Update: Hum solved. Needed an artifici...
