I had one of these back in the 80s. It was a good amplifier. I think that it used four 8950s. I ran mine at about 75 watts carrier. On SSB, it was good for about 300 "true/bird" pep watts.
It would be at least 29 years old by now, so I would plan on replacing all of the electrolytic capacitors for safety and to protect the very expensive sweep tubes.
In my opinion it is a great little amplifier that can be operated from a regular 120 VAC plug-in without putting much strain on your electrical system. I would buy one myself if I could find a really good deal on one!
I need info on maco 200. What frequencies/band is this amp usable on. All I have been able to find out is that it is HF. The one I have is in excellent condition, and I would like to use it on some of my radio equipment. Any info would be greatly appreciated.
Thanks Moonrunner48
Please advise me to what is a good replacement mic for my SR-497HPC... Answer: 497 is "wired like Cobra", so many choices available. That radio does not need a power mic, so purchase a stock "coffin style" mic with a decent cord, like the ones that Astatic uses. The Superstar DM-507 is my go-to. https://www.ebay.com/itm/3050474478...adANq91JSiEEnz8EGqPJRBloTgEyaVsBoCtoMQAvD_BwE $12.99 + .99 cent shipping.
