[JMS] Millen 90811 Amp

[Bill Bruno]

Hi George,

It's a neat little unit. I am at work right now but wanted to thank you for
responding so soon. The box looks like a factory production so when I have
some time at home I will send a pic of it to you.
I have not found anything on line about it. It does have a serial number
though.
Ok Better get back to work.

Thanks again.

Cheers

Bill
