I had an RM Italy KL-500, it worked well until my wife laid a leather coat on it in the middle of the night and I yacked the night away until it smelled like BBQ. I replaced the pills, BUT it blew the pills again a few hours latter. That's what I get for not checking it over a little more throughly (still new to working on amps)
But I can tell you this it's a great unit. I did not pay full price for it, BUT I think they are good units for the price. I think the solder joints where clean and the amp well thought out. BUT there are certainly better amps available, but they are hard to beat for the money
