Emporer ts 5010 audio mod

[Staybolt]

I need a mod to get more swing out of my cousins Emporer TS 5010.

 

[Shockwave]

The radio uses the same low level IF modulation scheme as the old Jackson export with the same MRF-477 final. Not much hope of making it a good AM performer without replacing the modulator stage.

Oh Puke.. This is my cousins rig and he loves it.. I hate the emp 5010 for that reason you stated.. Junk radio on AM.. However, i found a mod for the Jackson and got it improve a bit on AM...

They are a great radio, just never intended to be a hot rod heavy swinger on AM. Combine a proper tune and alignment with a decent desk mic and things should sound pretty good. Add an amplifier and it will get the job done.

If your cousin is a big AM talker then that's not a good radio choice. Any of the Stryker, Galaxy, Magnum, or Connex radio's with echo would be choices for loud AM talkers.

We just talked a few minutes ago on AM and his radio sounds very stocky, tight, and has very low audio even with my silver eagle i let him borrow however, his brothers is a screamer on AM.. I think his needs a tune up. Maybe some caps are bad as well. My cousin hasn't used his gear in over 10 years and most of it all has set in a box stored away...

would align the radio 1st and make sure the dead key is not to high. these radios if you try to get too many watts out of them the audio goes down very low. see how it does after the align. some of the jackson mods will work on this radio also if you did one on your jackson to the final area. not sure what you did..
also post what the dead key and swing is on the 5010 on am and what it does on SSB.

I was just looking at the service manual for this radio and just was thinking that since one person has one that talks good and the other does not. set the low mod one up just like the good one. a plus here since you have one to compare it too.

My cousin was trying to re-tune it the other night and smoked the final, lol. I have a spare to give him though. I think hes looking for another radio to just use on AM and save the 5010 to use on ssb...

Anyone ever try something like this on the 5010 works very well on the 2510

I did. But not needed when running stock final. Works great with MRF455 or more powerfull transistors.

I have done the MRF 477 swap to the 497 with changes to the board.
My opinion, not worth the trouble.
Swap to the 455/1466 is worth it " if " you can not run a outboard amp.
In all cases a outboard amp is better.
That's just me.

Any idea the part numbers or place to cut trace not laid out the same on this 5010?

 

[sp5it]

Any schematic for 5010?

I don't have one was comparing the link with pic from Rodger birds Mod I posted above of the back side of the board it's pretty different.

I can't help without schematic, sorry.
