Forté 1A power amplifier.... still good?

I have the chance to buy a (used but mint condition) Forté 1A power amplifier - to try some class A Nelson Pass magic - but I wonder if it still have a valid performance today.

Although this question can only be addressed after a proper listing session and with the right speakers, my main concerns are still of a significant measure.

So I kindly ask to any member to have or had a Forte amplifier, and those with experience and technical knowledge:

- is it easy to repair? I am considering the probability of a need for bias checking and also a recap?

- Are there any known mods suggestions, to improve any design flaw?

- what are the power consumption?

My aim is to pair it with the Thiel CS.5 and probably the Totem Model 1 (both 4 ohm  speakers) and the Rogue RP-1 pre amplifier.

Thanks to all.
