What are the original drivers?

What does RFI refer to apart from Radio Frequency Interference?

What exactly are you looking for?

Did you try what I suggested and disconnect ALL signal cables with your instrument plugged in the front end?

I would have thought that was obvious but good catch my friend.

You can check if you have the polarities correct by applying a 9V battery across the speaker cable. Both drivers should move in the same direction at the same time.

You know SWR is out of business right?

It appears that @Willowonly visited once and hasn't been back since! Sad that, we could have fixed him/her proper like!

Disconnect all your signal cables and run the amp with just the bass plugged in. What happens?

If the amp works as it should with your bass plugged into the Return jack try connecting the Send and Return with a signal cable and the bass plugged in as normal. Sometimes the normalizing contacts on these jacks can get corroded and fail to make proper contact.

The 6L6WGB is from an older less able family than the 6L6GC currently used. I may even have a couple of these tubes in my tube caddie. LOL Edit to add: If memory serves me correctly the W signifies a tube designed for industrial purposes.

Peavey do make reliable stuff!

I exchanged the amp I was using for the Bassman when I left the band. I figured the Bassman would have a higher value. Simple economics!

One pairing that you can take to the bank is never mix a 4x10 with a 1x15. It always puts the single 15 in danger as it fails to keep up with the more capable 4x10.

With modern drivers the need for an 8x10 is long past. A 4x10 is kinda overkill too.

Agreed. Use one 2x10 at rehearsals and both, stacked on their ends for a vertical 4x10 to gig with.

Absolutely!! You could try a so called 'Tweeter Box'. A small box containing a mid range and or tweeter plus suitable crossover. This would operate in parallel with the woofer(s) in the AER. You could try a couple of Piezo tweeters to see if they help. they don't need much of a crossover and are cheap.

Of English decent!! LOL

@Hellzero I don't hink I should be talking to you anyway. You defeated my country's team!

You should also get the shielding problems with your instruments sorted out. Also remember that if you stand/sit too close to your amplifier your you'll pick up interference from the amp.

Acme cabinets are special! LOL

Time to call the Guru. @agedhorse

Which, theoretically, the Amp Designer should have taken into account.

Hey Charlie, always nice to hear from you. I guess we all have our own preferences in amplification. The huge disappointment I felt the first night I used the Bassman affected me for life. I couldn't get the amp back to the store fast enough. I replaced it with a Marshall 4x12 driven by a Leak TL50+ power amp and I built a single tube preamp that derived its power from the pre-amp socket on the Leak. it was far far better.
