Gainclone built progress

I decided I won't spend $300 for casing but if you search the term 'Gainclone' in Google images there are heaps of excellent design samples. Mine uses Jaycar $15 casing which looks nice and tidy for its price.

The toroid and amps circuit fit perfectly.

30/12/07 - Managed to cram 4 channels of 3875 amps into this little box. It's a two-tier setup. The whole system now sounds really great but I'm having problems with hum on the second pair of amp (pulling hair...). Also I don't know why the new pair runs hotter even though they are exact same design.

7/1/08 - Upgraded the pots using two 100k ohms linear ALPS blue velvets. Result is not much difference.

The oscillation is the probable reason for the pair amps that run hotter than the other pair. Check the wiring and make sure so-called ground loops don't exist.
