Nice collection, I'm also have some boat anchors on my desk, i love tube equipment.

Fine, 700 - 800 watts is my current power, so there's no problem. Thanks for the replys!

RMS, Bird Watts.

Anyone knows how many "real watts" could handle this antenna before being burned? I think at least 1K, or maybe i´m wrong.

Take it easy, you are correct. There are a lot of things (voltage, power supply size, input drive,:shock: etc) to make a few more watts. But, like Beetle say: "For some reason, many people are obsessed with getting the last possible watt out of an amplifier" Certain words. Those few more...

Very good info. :wink: The Filament Circuit section is very interesting. Henry Amplifiers > More powerful. :) Heathkit Amplifiers > More durable. :D

Then it’s true. I saw in another site that the power supply in the SB-220 is only a little bit bigger than the one in the SB-200. Also I saw this (about the SB-200): :P "is a small amp with a power supply and cooling system that keeps things operating in an OK state" "Some would claim...

Talking about this, i have some doubts. :? I know that if a linear amplifier (in this case the SB-220) is rated for 2000 w PEP INPUT, mean that the output power should be the half. Well, i don't have a SB-220, but i have its little brother, the sb-200, that is rated for 1200 w PEP INPUT, and...

3500 - 4500 watts? :? I read that each 4cx250b can give 400 watts PEP output power. So, 400 x 6 = 2400 watts. Maybe 3000 w at maximun. Source: http://www.rfparts.com/tubespecs.html

Well, the last week i put a new set of tubes in my SB-200, and i obtain 7 times the input power, in 11 meters > 20 w in = 140 w out, 30 w in = 210 w out (carrier). I never use more than 200 watts in AM with this linear. With this i still obtain a few swing (aprox. 300 watts AVG). :)

Thank you very much! :D Plate: 500 ma max. Grid: 100 ma max. (white area in meter).

Bad, very bad news. :(

Which could be the safe meter readings for grid and plate for a Heathkit sb-200, in ma?

:shock:

Precisely i need a pair of 572B for my SB-200, and i buy them this past saturday from here > http://cgi.ebay.com/New-Matched-Pair-572B-Vacuum-Tubes_W0QQitemZ110183760133QQihZ001QQcategoryZ48710QQrdZ1QQssPageNameZWD1VQQcmdZViewItem :lol: Originally i want to buy a new Taylor set, but they...
