Default SE 833A Help

Dear Gents,

I would like to do a DIY monoblock SE with the following config:
833A or C /Kt88 or 300B / WE437 or 6C45. (150wpc) somebody has the schematics of the circuits and the power supply.
I hear that is not so easy and very dangerous, also im from Chile which difficults the things a little bit. therefore I will need to import a few things, therefore if also somebody has the picking list, will be also much appreciate.
Other things Wavac schems are the best for this or is somenthing better.

please advice and sorry for bother the comunity, I been searching the net without much success

Default The 833.........

This is going to cost you the price of a very nice new car.
The transformers alone will most likely be custom made, will cost at least a thousand US Dollars each and you will need several of them in all configurations.
This type of amp is only for the VERY experienced builder and asking a rookie to try it is like asking a regular fellow to jump into a Formula One car & go race it.

Honestly, that's the sort of amp to which the following rule applies: if you can't design it yourself, don't do it...
