Nice description. I had a Maverick about 50 years ago. Good amp. 👍
IIRC, the 6AQ5 is the tube that operates the keying circuit. From the manual, that's a post-1974 amp because that's when the radio power limits were changed from 5 watts input on AM/15 watts input PEP on SSB to the current 4 watts output on AM/12 watts output on SSB.
These were quite popular before 1972 because the most popular antennas could handle the power output. The CLR2 was rated for 300 watts and the Super Magnum was rated for 350 watts. If you wanted to run a Phantom, Skipper 300, or bigger you needed a beam, Mosley Devant, or the Astro Plane. That changed when the Penetrator and Starduster were introduced in 1972.
You can also use 6KV6's for the driver tubes and 6MJ6's for the finals if you can find them. Both are heavy duty versions of the tubes you listed. I had one of these about 50 years ago. Also had the Phantom, it's big brother.
Best video on tuning these that I have seen.👍
Thanks, there's a lot of dis information out there, but documentation doesn't lie :)
This is the best video for this amp I have seen on yt. Would this be the same tuning sequence for the newer brown face Maverick dual power amp that came just after the grey? Also did you set the swr calibrate while the amp was keyed up? Again, thanks for sharing all this great info' about these fine amplifiers! 73 160 MI. ✌

My rear 6lq 6s don't light up what do you think's wrong with it
Could I possibly get a copy of the manual
I just acquired one of these. I really don’t know much about it. All the tubes light up. That’s about all I know. Any chance you could provide any docs on this thing?
Back in the cb days I had one worked great till I accidentally had to many beers one night and drove about 150 watts into her. She wasn’t happy about that at all.
Been there, done that, replaced the caps and tubes :) had 900 watts for a few minutes!!
Any way I could get a copy of that manual?
Do you have any amplifiers for sale now?
Sorry, no.
