VTL 300 Deluxe monoblocks

Could anyone recommend someone that could work on VTL 300 Deluxe? They are currently working. I power them up with a variac so the caps don’t blow. However, they should be updated with new caps, internal wiring, etc. I don’t feel competent to DIY this,
so am looking for a professional. BTW, VTL will no longer do work on them. I guess they want me to go buy one of their newer models.

In 1993, Manley Laboratories, Inc. became a separate entity apart from VTL. The new Manley Labs factory at 13880 Magnolia Ave. in beautiful and bovine Chino, California
After only three years with Manley Laboratories, co-founder David Manley abruptly left the company and the country in 1996. With EveAnna Manley now at the helm, the modern form of Manley Labs began to take shape.

Your right Eve-Ana Manley took over the VTL factory after David passed.
And it became Manley Labs and in 1993 she separated from VTL, they must have shared the same old factory.

VTL died when David Manley died. VTL has their days numbered.
Eva Manley took over from David when he passed and did a good job, then I think the son took over.

This is the one I looked at.

Maybe that wasn’t the one I borrowed, it was back in the 80’s🤷‍♂️
And for memory now, it did have a very catchy title, not what that white ones got.

No specific schematic in the book. There are a few reviews by J. Gordon holt and TAS.
Wrong book the one I had was his first I believe. It was full of schematics, and no reviews for memory either

VTL 300 Deluxe monoblocks
Great amps David Manley’s best I thought, sounded stunning into a pair of Maggie Tympani 1D’s.
(OP Transformers were the secrete what a beast) 
Any good tube tech will be able to look after these, see if you can get hold of Manley's Tube book he wrote, has all the circuit diagrams in it for these and others.
