MIJ Elk 15W Tube Amp w/trem and reverb for R3800...and it's been re-capped & serviced.
Some info on the Elk, including internal pics of the wiring and tube configuration (12AX7/EL84)

I've seen one listed at USD500 on reverb, although asking that price would be rather ambitious locally!
There's not a huge amount of love for Elk in SA, but I've had the "cheap" 20W transistor version and that seriously impressed me - great little unit, well designed and really well put together. Recapping is a must though...while build quality is MIJ, caps do eventually age/leak - it's just how it is with old amps.
Aaaand that tremelo and (very springy) reverb are both really unique and fun sounds, pedals just don't quite capture that sound of nostalgia
