Can anyone give some basics on this amp, correct power tubes, ?x2 6KV6A? audio tube, 6AQ5 or 6BQ5? Fuse size?Correct size Caps? How many output watts? Original date released,price? I recently found what appears to be a nice orig,non modified Browning MarkIII/ 180 Amp set, here in the midwest, going to see it,and check it out, Hope its one of those rare finds, that comes along once, in the rare long search process for that perfect radio. Thanks to all here for your expertise and understanding to keep this great hobby alive, DQRR

Hope that you luck out and find the elusive rare radio and amp that you're searching for. We haven't talked since that band opening a couple of years ago but It'll surely happen again. I've been sparse on chasing skip lately. Not feeling too good. I lifted an air conditioner a week ago and now can't turn my head. I already had two disks taken out and the doc set me up for X-rays on Friday.

The Browning 180 uses 2 6JG6A tubes and one 6BQ5. IF you can't find any 6JG6A tubes you can use the 6KV6 (preferred) or the 6JT6. The amp should deadkey around 35-45 watts, with peaks between 80-125 watts.

Hello Tombstone, Sorry to hear about your neck problem. I know that pain myself, I hope you the best on getting it taken care of. Yeah its been a couple of years since we made that long DX contact, it was thrill for me to talk skip with someone from this Forum, Here in StLouis skips been erratic and only occasionally do I yell out for DX. Take care, I hope to hear ya out there in the future>DQRR Thanks cbrown for the helpful info. When I try out this Mark lII/180amp set, I wanted to have some more info on whats the norm for this amp, I had one for awhile, didn't use it much. It did about 60W, Later I sold it to Fixer, hope he got it squared away. Thanks again ALL YOU GUY'S Keeping the hobby alive. DQRR

Thanks for the good wishes deltaqueenriverrat! I'm feeling a good bit better this evening. The muscle relaxers are working and the X-rays will tell the tale. I wouldn't mind having a 180 amp myself but that'll have to wait, too many other projects going. I'd bet that we'll be on the air at the same time sometime this summer and we'll hook up as before. I'm using my Browning R27, S23 tonight and skip is really rolling on the old 23 channel band and below. I made a couple of DX contacts with the old bird barefoot so that satisfied me for now. Hope that you find the amp and also hope that we can hook up again. It's rare that I hear "OT" callsigns.

The 180 amplifier would bring stupid money on Ebay unitl they started getting kicked off.
Every year that goes by you'll see fewer and fewer specimens that have not been smoked by some idiot that used a 30-Amp (no-blow) fuse, or hacked by an idiot with a soldering iron and diagonal cutters.
Biggest problem is that a 1972 linear with all "original" parts is a lot like a 1972 car with "all original" parts. Until you rpelace every hose, belt, seal and bushing you don't dare drive it anywhere.
The 180 will need all the electrolytic capacitors replaced before you try to use it, even if it's "NIB, NOS". That kind of part is not meant to last 20 years, let alone 35 or 40. Just don't let anyone talk you into using cheaper 450-Volt rated filter caps. This one requires the slightly more expensive caps rated at 500 Volts.
Some 6KV6 tubes may be too tall to fit inside. But it is the best choice of the handful of 'substitute' types that will fit and work in the 180.
And if you find one that looks clean, remember that it's not just the miles, it's the years, too.
