DL4 distortion problems part3

["cameron street" <c.jas@optusnet.com.au>]

[Part 2 was'nt delivered, i guess, cause i used the f word]

I have 2 DL4's,  The new one distorts in the top end,
Tried them both separatley, with different power supply's,
with and with out batteries.
the new one clearly distorts in the top end!
With no effects, straight through , dry.
Tried lowering the gain into the unit,  no difference.
Sent it back for a service, locally. but i'm in australia.
Do LINE6 tack units back for repair, are they cool?
