New build: 6F3P + 6ZH8 + 6N2P

[Miyagi_83]

Hi everyone,
I'd like to make a bit of a contribution to this great forum and share my build. The schematic as of 20 December 2021 is attached.
As you can see, it's a very simple construction. Here are some sound clips recorded with a banana skin

In all of the above samples, the PPIMV is maxed.
The guitar is telecaster-shaped with a maple neck and maple fingerboard (and it's a little out of tune). I don't know what the body is made of It's got a Warman Destroyer humbucker in the bridge and Warman ceramic humbucker-sized P90 in the neck position. The amp is plugged into a 2x12 cab loaded with Eminence Governor and Swamp Thang (or Texas Heat, I can't remember for sure) speakers.
The playing is sloppy, but they're mostly improvised riffs and licks, so bear with me

The preamp will probably undergo some tweaking, but I need to find enough time to do that. I'm thinking about an LND150 tremolo. I don't have space for reverb though. I'll upload some pics later.
Enjoy.

Fine, thanks for sharing

waiting for photo (and a layout if possibile)

While taking the pics I realized I'd messed up the schematic I put the PI grid stopper in the wrong place. The updated schematic is attached. I'm also attaching a few pictures. I'll put up a few more in a second. Enjoy.

Here's another one.

And these are the last ones I've got.

Thanks for the support, Franco

I'm working on the layout in DIYLC, but it's taking time. I'll post it as soon as I've done it, but I can't promise it's going to happen before Christmas.

I tried to listen to the SoundCloud clip, but it looks like it’s “private”.

Sorry about that. It must have been private by default. Try now.

Thanks for posting.  Clips sounded good.  Congratulations on a successful build.

Nice clean construction 👍

Happy New Year everyone!
I have finally managed to finish the layout for this amp. I attached it in PDF format. Enjoy.
Special thanks to tubenit for sharing his layout for the 6BM8 version of the HoSo56 amp. As you can see, my laout is heavily inspired by that

Now, I've been thinking about adding LND150 tremolo as designed by 2deaf to wiggle the bias of the pentode stage. Something along the lines of Fender Vibrochamp meets Vox AC4. According to the schematic I've found here

https://el34world.com/Forum/index.php?topic=23811.msg256428#msg256428

the voltage he uses is 400 V. In my amp, the voltage at the first filter cap is 260 V. Is there anything I'd have to change or can I use 2deaf's values?
Thanks in advance for any help.

EDIT: I've updated the layout because of some value and wiring errors.

[Miyagi_83]

Ok, so I modified 2deaf's schematic like this to suit the lower voltage. Because I know next to nothing about tremolo circuits and even less about MOSFETs, could someone more knowlegeable than me take a look and tell me whether it's going to work? If I've made mistakes, I'll appreciate any hints and suggestions.
