36w 2ch Normal + LiteIIb w mods

[elmango]

Hello. 1st post, introduction:
Came to know the 18w while searching marketplaces for a JTM-45.
The ad said something like "18 watt Marshall TMB". Never heard of, but good price and nearby so i bought it. NOS Mullard EL84s, Heyboers, Sozos. The chassis was marked with "Ceriatone '09". The build was not perfect. Ugly distortion and squealing when cranked. TMB channel had a hiss present at all volumes.
A little googeling led me on the path towards amp building. About a year later the amp was dead quiet and healthy sounding. Completely disassembled and rebuild. Made possible by the great knowledge of people on this and other message boards.
The drawback is i caught a fever. And the only prescription is more amp building.

In the process of fixing the 18w TMB i've tried stock Ceriatone TMB, Richie Halls v5 with NFB, normal and trem tone control, conjunctive filter etc etc.
I've found i like the different versions too much to live with just one of them, so a 2nd amp needs to be built.
I'm thinking 2ch 36w EL84. Normal channel (original tone control) with switch for shared/separate cathode. + LiteIIb channel with shared/separate cathode switch + parallel/cascade switch.

I did my best to make a schematic. It's a first for me so i expect it to be lethal in its present state. The power supply is excluded for the sake of simplicity.

I'm grateful for all inputs you're willing to give.
Thanks /Magnus

It's a very addictive hobby - so much so I've been thinking very strongly about making it a non-hobby!

Someone stole V5 on your schematic

I'm not really clued up on the Lite2b but was wondering if the differences on the two channels in terms of tone/vol section are deliberate/necessary? If both channels could use the same tone/vol setup it'd simplify the layout and front panel.

Good catch with the missing V5, when correcting the tube numbers i also found a missing 100R from the normal channels tone pot to ground.
When playing around with the normal channel in my 18w TMB I've found a sweet spot at lower volume that i just cant find with the trem tone control. It's a clear and thick tone that sounds great with neck humbucker. But that sweet spot aside, i find the trem T/C superior.
That's the reason for keeping the dual channels. If it would've been possible to switch between the two tone controls...?
But i agree, it's a lot of fuzz for a small detail.
