The manual states no more than 4 watts AM, and no more than 16 watts P.E.P on SSB. It also says expected output power is to be over 250 watts on high power and 50 watts on low power.

Expect to replace tubes if you drive it higher for any extended amount of time, and they can get expensive. I used to drive it with 6 watts and never experienced a problem.

Someone mentioned a manual for a D&A Mavrick 250. Who has one or can copy it?



Thanks

I'll scan it tonight, only about 4 pages. Just tell me where you want me to e-mail it.

WOW, I know this is an OLD post but I too have a Maverick 250 and would LOVE to get a copy of the manual. Mine wants to "squeal" when I get it close to being loaded to what I think is correctly and I would like to make sure I am doing it right. If you still have a copy, I would love to recieve it email or snali mail and if you no longer do,
then thanks anyway and God Bless

Hate to resurrect an old post but I too could use a copy of the manual if anyone can help out. Thanks in advance.

The design of this model evolved over the ten years (or so) they made it. There is no single diagram that's correct for every version.

Here's the old, but not oldest version. http://www.cbtricks.com/Amp/d_and_a/maverick_250/index.htm

Like getting the right shop manual for a Ford F-100. Helps a lot to know the model year. No VIN label on a Maverick.

But with a D&A box, you need to use other clues. Early ones had a single skinny 6AQ5 (or 12AQ5) tube in the rear. It serves to activate the relay when it's triggered by the radio's transmit carrier. Uses two relays with 9k or 10k ohm coils rated at 110 Volts DC (NOT ac).

Later versions had a transistor to key the relays, and the relay coils were rated for 12 Volts DC.

There are other production changes.

The diagram in the link has the small tube to key the relay.

Or you could click on the hyperlink in the post above.

Hint: it's the line with 'cbtricks.com' in it. Click on it.

That wattage is stated as "input" wattage (a ham term) which translates to actual RMS wattage out to a dummy load as 100 watts on low and 500 on high. You may get slightly different results depending on tube life and meter differerence.

This thread dates back to 1969?!? Whoa!

When we switched the forum software years ago the oldest posts defaulted to 1969 when the Flux Capacitor fully charged.

That is a good thing. Seems every time I try to research something about older equipment, the threads stopped years ago and nobody has updated them since with better and more proven information, especially about amplifiers.
