DayVit · 19th February 2010, 08:27 PM

Hello,

I have this plan to convert my Yarland FV34AIII to a pre-amp. Not sure if this realistic, if anyone has tried before ... let me know

I have a friend who knows what he's doing, at least i think he knows.
Anywey, for this a schematic would be very helpfull.
Can anyone help me with this?

Thanks!

regards,

Dave

I think the Yarland amps have all their components and tubes mounted on PCBs, so basically all you will have left after removing that and the output transformers, will be the chassis and power transformer. You may be able to pull all the components off the PCB and reconfigure it as a pre-amp using other tubes, but it seems like a lot of work, and PCBs made for a power tube (EL34) will be very messy once altered to accommodate a pre-amp tube.
