Re: Looking inside Alessandro Bloodhound
Did this amp use a choke? I've seen a schematic of an Alessandro amp that sounds very similar to the circuit you described. It showed 40uF of filtering right after the rectifier (two 80uF caps in series) followed by a choke and 20uF of filtering. The OT B+ was taken after the choke.  
 
The preamp looks like a Trainwreck Express topology, but the 3rd gain stage uses a 1.5k cathode resistor bypassed with a 25uF cap instead of an unbypasssed 10k cathode resistor.
