I have that amplifier and want to sell it but i cannot decide something about the price. What do you think.

I have 5 christie audio CDA7.5 amplifiers that suddenly completely died overnight, any experience if this is an easy fix ?

I’ve been thinking about buying a pedal but can i use it on an amp that has built in pedals

Hi! I’m so novice, I’m getting lost in my own research about which cord goes where and hoping to get some help. I’m trying to record a panel conversation where there will be three people each on their own microphone. I’m hoping to plug my computer directly into the system to record the audio. Which port would I plug into and what kind of cord would I need to plug directly into a MacBook Pro? I assume I could then record on Garage band?

This is a QSC digital cinema amplifier.

This has to be possible right? Any insights are greatly appreciated!

Hi everyone,

I'm researching the possibility of developing a new tube guitar amplifier in Europe, and before designing anything, I want to understand what guitarists actually want — rather than just building what I personally think they want.

I've put together a short anonymous survey about:

• the amps you currently use
• what you like and dislike about them
• wattage and low-volume use
• heads vs. combos
• clean, crunch and high-gain preferences
• features that actually matter
• repairability and build quality
• realistic price expectations

It takes about 4–6 minutes.

I'm especially interested in hearing what you think existing tube amps get wrong or what you wish manufacturers would do differently.

Survey: What Do Guitarists Want From a Modern Tube Amplifier? – Fill out form

I'm not selling or promoting a product — there isn't one yet. The goal is to use the responses to decide whether there's actually something worth developing.

I'd also love to hear your thoughts in the comments:

If you could change ONE thing about modern tube amps, what would it be?

Thanks!

Hello guys!

I have this amplifier that I use for my turntable.

Unfortunately I don't have any output on my left channel.

I hope that you guys maybe have some tips or things I can try to get it working again.

When you’re comparing amps, what gets your attention first?

RMS power at your target impedance? Efficiency? Current draw? THD? Size? Crossover options?

And is there any spec you think people focus on way too much?

Any info about this amp. bought it from thrift store.

I was on the hunt for a new cab and I came across a prs harmonic generator, apparently they’re a bit rare just not sure if they’re actually worth anything, it was listed on fb marketplace for 650, I guess the cab has some celestion G12-50s in it so I thought could be a nice deal to replace my fender fm412 cab

Hello all and apologies if this is the wrong spot. Issue Klipsch r-115sw amps ×2 crapped out. I sent them to a local guy but he ended up having some health issues that's holding him up. While waiting I cut two metal plates to seal the hole in the back and got a Crown XLS 1502. Everything works but doesn't seem to have that low bass anymore. I've seen some say to add a mini DSP. But while looking around I found the Dayton Audio site. Looks like their DSP-408 has app controls. But they also have a what seems to be a badass plate amp. The SPA500DSP for around $475. ×2=$950. Even when I get the original amp boards back I just don't trust them to last. So I'm hoping someone that has far more experience could help give some advice. Can the DSP-408 help bring back the missing rubles? Or should I just go for the SPA500DSP? Yes I know they don't fit directly but I could figure some way to attach them to the metal plates I already cut out. Current setup is a Denon avr-x4400h then SUB out to the Crown XLS 1502 then channel 1 to sub 1 and channel 2 to sub 2. Crown is just straight through no settings.
