British Style PCBs - available types?

I just ordered the British Style PCB and am trying to work out the different types of amp that can be built from it.

JTM45

Plexi68

Plexi69

JCM800 2204

JCM800 2203

But when I look in the docs (https://www.aaelectronicspcb.com/resources), there are these 4:

JMP1987 (bass) 50W

JTM45

JCM800 (2204) 50W

JMP1987 (lead) 50W

I assume: Bassman = JMP1987 (bass) 50W

JTM45 = JTM45

JCM800 2204 = JCM800 (2204) 50W

and JMP1987 (lead) 50W seems like an extra one, not in the main ad.

Are there schematics/layouts/bom for the following?

JCM800 2203

Plexi68

Plexi69

Thanks

Hi,

The Bassman is the same model of JTM45. The difference are :

-12AY7 on V1 instead 12AX7

-NFB resistor 27K on 2 Ohm tap instead 16 ohm tap (you can use 56k on 8ohm tap or 75k on 16 ohm tap)

-A cab with 4 Jensen 10" speaker instead a head and a 4/12" Celestion speaker

Thats all

For the JCM800 2203 is the same of 2204 : a 100W head and the 2204 is a 50W Head
