    Well I'm enjoying this exercise more and more as I'm slowly learning How the amp works. I'm sure Glenn has some fantastic ideas as to how the amp could be improved and that's what I like. I love the idea that I can talk and discuss the mods and see how they work. Part of the whole hifi experience is knowing that I tailored my equipment to my needs it's very satisfying seeing how your ideas turn out especially at the end of a long winters night when your completely chilled out listening to your favourite tunes.

    With a favourite tipple of course Andrew I like this type of thread since it points the way to people who buy 2nd hand gear ( in this case Croft ) and want to upgrade it .

    Well I got another email and the fully monty includes :-

    Seiden selector switch.
    Eichmann phono sockets.
    Khozmo attenuator.
    SCR Teflon output caps.
    Rike PIO coupling caps.
    Clarity Cap TC4 power supply caps.
    Separate transformer box with separate 500VA transformers for each channel.
    Separate hybrid ht supplies for each channel.

    Precision wirewound resistors.

    Individual heater regulators for each valve.


    I'm not sure if Glenn can push things further but sounds pretty exhaustive. I still don't know how he's going to populate the Khozmo attenuator, I'd like to know his resistor selection. Additionally I have no idea what " Individual heater regulators for each valve" are and God only know's what "Separate hybrid ht supplies for each channel." can be . I presume that they must have something to do with the SS regulation that some of these high end Crofts seem to have around here . I have some pictures for later so I'm off for an hour to get some work done.

    Err that sounds pretty comprehensive to me.

    Might be up there with your spec Jo

    Hmmmmm...... quite disappointing but also reassuring. I hope this is as far as Glenn can push things (the reassuring bit), but I hope Glenn's just not copying your amp - the disappointing bit. It would be interesting to see if Glenn's making any compromises with these parts or if's he's selected these with the knowledge that they are definitely the best bits for the job.

    I can tell you Andrew I have known many of the amplifiers Glenn has built over the years having had his original micro nearly 30 years ago and I have heard many of his pre and power amps although not all his specials.

    If you really want to know how far he can go with your pre speak to Adrian Parsons at Audioflair and i can tell you some of the components can be eye watering in price and his amps can be mind boggling in complexity - take a look at his Absolute 1 pre amp with 8 transformers and an unbelievably complex circuit. It all depends how far you really want to go and how deep your pockets are. Some of the caps are £1000 a pop!

    Ultimately however its all about how the amp performs and sounds and this is where fine tuning may come into play especially with its interaction with the rest of your system.

    I could say a few things about that, and about the 'Amar era', in general...

    Let's just say that Glenn's head was not in a very good place then (and for valid reasons)!

    Marco.
    Your right Marco - the past is probably best left alone but some of Glenns creations were absolutely amazing and shows what a genius he really is with valve amps. Don,t forget your amp and Jo,s in their orginal concept were created in that past.

    I have to be sensible and am I really going to see a massive difference if I plonk in a £1K cap when a £20 cap will do just the same job? I'll have a look at the Audioflair website.
