Liverpool - vvr - scratchy pots

[gary]

Hello gang

this is my first home brew 'whole amp' vvr attempt on a Liverpool clone. Just want some re-assurance about the locations for the scratchy pot filters. Am I right that I will need one on the input and one on the volume pot wiper?

Thanks

yes. You want a cap between any pot (guitar or in the amp) and the grid it feeds. This will block the DC grid emission.

Don't forget to also add a 1 Meg resistor off of the grid to ground
so the grid will have a DC ground reference.

Let me know how you get on Gary! Would love to hear it powerscaled sometime!

[gary]

Thanks guys.

James - it's the only way I'll ever get the benefit of your handiwork! I'll be careful with it.

Put this on my Rocket and it cleared the DC.

Thanks for the picture - especially helpful to us novices

I know that the paint by numbers is frowned upon, but it really does help clarify concepts to see the components in place ( for me ).

I find layouts really confusing much prefer schematics but i understand why many like them. What ever works for learning everyone learns differently

[angelodp]

Yes, ultimately the schematic shows all.
