musical fidelity E1 E11 RE CAPPING YOUR AGEING AMP

whats gan on · 25th December 2007, 08:45 AM

i bought a musical fidelity E 1 amp to modify it to see if i could get a performance of amps costing £1000's with BHC 22.000
i recapped the 10.000 mf capacitors also fitted a 500 va transformer alps blue volume pot and four new output transistors
before i modified this amp the sound was bright hardley any bass to fill my big room.
the transformer is far to small for this amp
i have compered it to a roksan kandy mk3 power amp with a quality passive pre
and this MUSICAL FIDELITY amp is far better before the upgrade the roskan left it for dead
all coments welcome

Hello, Congrats for the good work. Do you have any photo?
I'm sure you can go further in the mods, think diodes, non polar caps, etc.

This is great, I'm looking to get an E1 myself to go with my T1 tuner. I shall copy your mods if that's OK. Good work. Well done. Barry

Hmmmm.........

One could argue a 500VA transformer is way over the
top for such a joke of a heatsinking arrangement.

New same as output transistors will do nothing ......
