Dual Bias Layout for DR103

[Univibe65]

I was thinking about a smart way to install the dual bias circuit in my DR103 without any major changes or an additional board - and had this idea here:



The pots will be mounted in the spare holes of the chassis (preamp-tubes).

What do you think. Is it alright?

Looks good to me.

OK - it's 4:40 am now and I'm done.





Now the amp is almost ready - dual bias, new caps, input section rewired and mains plug installed.
Caps still need to be formed and I have to order some Imperial 2BA's from the UK.
I can't wait to play this thing live.

Thanks for your help, Mark.

One more thing - I recognized that the (replaced) Master Volume pot has 500k instead of 250k. Does that hurt?

Nah, that shouldn't make a big difference.
