Good morning all
Its been quite a while since my last post.
I am currently planning on building a Marshall 1930 combo clone for home use. I am thinking of using modified build from Bo Hansens work (I've been in contact with him but he has now 'retired' from further work in this area) but would like to swap out the ECC82 for an ECC83 to increase the front end gain (schematic attached). Can any one offer guidance/assistance how can readily achieve this please?

Many thanks

Rob
