Question about your new AVC preamp
« on: 8 Jun 2008, 06:11 am »
Hi John,

Are you planning to use a Shallco 23 position switch with the new AVC? I see on Dave's site that his AVC has 28 steps. Maybe you're using a modified AVC or a different switch altogether. Forgive me if you don't want to discuss the details of your baby before it's released. Feel free to ignore if you prefer to wait. 

All the best,

John Chapman

No problem at all with the question! I am using modules like those used inside the S&B based TAP units. It's way cleaner signal path wise with Dave's AVC and Dave and I came up with a way to get 1db steps from -52db all the way up to +7db continuous. Also gives right/left bal control and smooth quiet operation. Still 100% passive signal path. Very happy with the new units.

I am doing my best to catch up here and be able to update the web with the new stuff. I am not doing very good at it though! Each day / week seems to be consumed keeping up. Soon I'll run out of a few parts and that will give be time to get to it.
