[QUOTE="El Sid, post: 830048, member: 18550"] Hello handsome ( ;D now I know why you chose that name) Thanks for the feedback - I am looking forward to getting this going. I'll try and get my hands on both rectifiers and try them Another imho nice touch is the balancing pots on the phase splitters I'll do more work on the driver valves. I also thought the 680k load resistor was very high. [b]More questions:[/b] Something else i found in the power supply section was a 500k resistor connected to ground with the other end having come loose and just floating around. I think it was probably a bleeder resistor connected to the 90 ohm resistor/external caps - does anyone agree? I was thinking of adding two caps - one before the choke and one after (as I've seen done). Circuits without the choke have anywhere between 60-80-200 uF in the supply. I was thinking 100uF. But is that excessive given that the choke is there? I suppose it comes down to how little ripple you want. Suggestions? Anyway, when I get going I'll move this to the DIY section. The more I look at how cool that old iron is, the more I think I'm going to make an awesome new chassis for it [/QUOTE]
