Spectron Audio Out Of Business?

Hello,
Three shops that I have sent one of my Spectrons to are unable to carry out repairs on the power modules.
It is now believed that the large black custom IC is defected.
There is no info printed on this component and none of the techs knows what it is, apart from hand written sharpie numbers  470 and 465kc / Nat 33c and 464kc, these must be Spectrons coding.
A fellow tech at work replaced all 3 Wima caps and the 2 power mos fets and still no go, he also thinks that the unknown black IC is at fault.
I am really hoping that we get lucky and some ex-Spectron tech find this forum who may be able to help us.
I wonder what has become Spectron's inventory of spare parts, tools, testing equipment etc?
Both of Mr Manh's numbers are disconnected and emails bounce back.
The amps were assembled in CA so there must be several ex-employees around.

I’m just gonna sell mine for parts....

Keep your eyes open.

@celander  trying to get my ExactPower recapped and fixed for 4 months now by a member i found here that's an alleged expert. 4 F'in months and I am still waiting. 

do you think Deltronics can recap w/ larger caps (over 1000uF)?

i need to get my unit back from this shyster and send it to a legit repair shop.
