The standby switch could switch out the output tube cathodes or even their screen supplies. Switch on the centre tap of the OPT is yet another.

Let's ask the man himself: @agedhorse

Enjoy!

Some amps have a delayed turn on of the speaker jacks to reduce turn on thumps from getting to the speakers.

Don't cut anything vital off!!

Identical cabinets always work better when paired. What is the minimum impedance of your amp?

I have o admit that the demo left me cold. I'm not interested in amps that sound like I'm playing through a fuzz box.

Glad to have been of help!

I took my Korg tuner out as I usually use a Snark clip on. In its place I fitted 1U ventilated vent to allow more air to circulate within the rack case. That's never a bad thing.

If you plug into the front end of the amp the pre-amp will be active. Plug into the external pre-amp and feed the unit's output into the Return.

Ventilation!!

My choice ia an Ampeg B15NF.

Cranking the Bass full on is going to demand more of the speaker than it may be able to handle.

Not really. I was moving out of the city and not going to be playing any time soon. It was a mutual agreement.

The best sound I ever achieved with a 50W amp was a Leak TL50+ I bought in the late Sixties for five quid. I built a single 12AX7 pre-amp to drive it and powered from it. Those KT88s handled everything and more. When I left the band the leader got me to exchange my set up for the new bass player's Bassman. I thought it would be worth more than my stuff. he got the best of the del!

Earlier in the thread @matbardsaid that the amp had arrived too. I wonder what his/her experience was with the amp?

Just for interest is the speaker compartment sealed, ported or open backed? I'm sorry that your experience was not that you'd hoped for.

It's hard to get good help!

You know Jack, I'm glad you're happy and all BUT, every time I see your dancing icon I think there's a bug crawling on my screen!! LOL Thank you for the gig video. It did my heart good seeing the big red busses trundling behind you. It's funny what you miss when you're away from your home country or city.

Nancy you know the rules! No photo, it didn't happen!! I hope the set up serves you well.

No never.

That's because it is. The output from a 2x10 and that of a 1x15 is about the same. A 1x15 has no hope of keeping up with a 4x10 no matter how hard it tries. The pairing usually has the fifteen failing after a time. Best pairing you can get is with identical cabinets.

Many, many players think that a larger cone equates to a greater ability to produce lows. This is far from the truth as there are 15s that go higher than an average ten and tens, like those used in my Acme cabinets, that will happily thrust a Low B all day long. Secondly matching cabinets always work well together whilst dissimilar may not. Try stacking your boxes on their ends so that the drivers are vertical. You may just love the result. I certainly did! I love your Warwick. My Streamer is still the best sounding bass I own. It's tuned B E A D as I usually now play my six string basses.

What, if anything, did you think that the 15 was going to add to the 2x10? Curiosity feeds the question.
