There was no corrected schematic.  The PowerBlock was discontinued before they reprinted the manual and schematic.

At present I'm running my Crate into a 12" wedge monitor, but have just bought a pair of LDsystems 10" pa cabs to use instead!

I'm not concerned about stereo, as I plan eventually to run my voice through the Pod as well as guitar, and of course the HD500 allows you to have multiple setups depending on the individual song.

you can still order new Power blocks from musicians friend or by ordering them at your local music store!!!!!!!!!!!!!!

I'd had mine for ever and never had a problem with mine ( I always bypass the preamp section )

Tried to find it on musiciansfriend http://guitars.musiciansfriend.com/product/Crate-CPB150-PowerBlock-Stereo-Guitar-Amp?sku=487829 and it says "We're sorry, this product has been discontinued" and there's no order button. 

In music stores in my eastern European country you even have to wait for popular products such as line 6 actual models for couple of months, so this also fails as an option. I tried my luck, and the answer was “Crate Powerblock?? It has been discontinued long time ago”

Found a couple of second hands on ebay, but all of them are from the states and in combination with, again, my country's import laws and taxes this would be impossible to receive it, or eventually return if the unit is not in working order.

Thanks for the enthusiasm, anyway.
