Default Help me,Art Audio Concerto

Newbe-I have a MK1 Concerto in need of help!A circuit would be good.The amp has some boutique components fitted by former owners and my have the wrong valve line up.I say this because the front end valve Ecc82 has a very large anode load resistor 390k. What is the value and rating of the 4 psu caps and the filter resistor? The cathode bias resistors on the 6550's are 500R is this correct.
thanks, KT.
