My Setup around 1980  (Great times) Smile 

15A Homemade Linear PSU   
I think the rig was a Lafayette 1200 (I had a few different rigs and its a long time ago)
Zetagi BV 2001 Valve RF Amplifier (1KW SSB, 600W AM)
Hooked up to a 1/4 wave on the roof  
Not shown in this photo but I had a Leson DT251 desk Microphone (Such a clear load and distinctive sound in its day)

Certainly looks like a Lafayette 1200 there Paul. 1980s set-up 1KW SSB 600W AM RIG 1f44d 

"CQ, CQ, CQ, Running One-KeeeeloWaaat" favoured by many an Italian running Zetagi's and Bremi's. Very Happy

I don't know who was measuring power output back then but exaggeration was the key of the day. With 4 x PL/EL 509/519 Colour TV tubes you were lucky to get a true 350-400W PEP pushed hard with 20W input. Those that tried even harder often blew the input attenuation resistors and the 'modified' High Tension voltage guys might well have shown almost 1kW peak on a meter that couldn't distinguish frequency so measuring the terrible harmonics that could get kicked out.
affraid

TVI heaven. Wink


Thanks for sharing with the group, look forward to more.

73,
Victor


(Wasn't the Leson desk mic the same as the Ham International 'Big Puncher'? I think Altai used to manufacture them all.)

And I thought I was a bigboy for a while back in the day with my B550P, lol. You had a very nice setup, thanks for sharing the old photo.
