Marantz Model 16 power amp

[[email protected]]

I'm presently repairing my old Model 16. From reading the group's
posts, I gather that this was not one of Marantz's better amplifiers.
I was wondering if anybody would have any suggestions for mods that
would improve it. Thank you.

I don't know a whole lot about it, but if it's one of their earlier
japanese solid state amps, probably the best option is to remove and
static-bag everything but the heatsinks and power transformer and build
a better circuit inside the chassis. In the unlikely event it becomes
valuable, you could restuff the original guts in it.

Probably even the Slone/Self circuit discussed here some time back
would be better, although it's hardly a sonically superb affair.

It wasn't Japanese. It was built in California. As I recall it was 2 small
monoblocks bolted together to a single front panel. Very tight inside. Full
complementary outputs, with a first generation op amp IC at the front end.
Sounded awful. Filter caps were prone to failure and it wasn't very good
into low impedances. The OP is right. Not one of their better efforts.

You mean it measured OK and sounded awful?? O Kroo...explain this one,
please!
