Maplin Millennium 4-20 amps ?

[Swithers]

Hi to you all.... Has anybody ever made or used this amp kit ?, I have just got a pair that have been built as mono blocks ( somebody has made a very nice job in building these) They run class AB1, Valves used are 2X el34 1x ecc83 1 xef86 . I have been running them along side my leak st 20 & have to say both amps have things i like about them,after running the maplin amps the leak sounds abit hard & thin but has more top end. The maplin amps sounds deeper and sweeter if that makes sense ?. The voice sounds great on both amps. Have turned them off for the night now as my head is spinning, Guess i need to play each amp for a week or two then swap over ?. The rest of the system used is a Marantz cd17 , A home made passive pre amp & Tannoy 611 mk2 floor standers. Thanks Steve....
