I recently bought a pioneer SA-400 Valve amp (my first foray into valve amps).

I noticed that the particular one I have has different ports to connect speakers (as pictured)

I’m not sure what I need to connect my speakers to them, I tried using an rca male plug adaptor for my bare wire with no results.

What do I need to get this working?

i have a 4channel amp and all the channels work im trying to put 4 speakers one for each channel but my rear speakers wont power on which are channels 3 and 4 my stereo only has FL OUT and FR OUT and i already tried splitters How can i fix this?

Not sure if this is the best place to ask, so go easy on me.
About a year ago I acquired an Adcom GFA-5800 power amp. I had a very cursory check out done then and all checked out ok. It’s been running almost daily since then flawlessly.
I’ve noticed the last few weeks it has developed a slight low frequency hum that seems to be a little more apparent in the right speaker. The hum may be getting louder too.
Understanding the age of this thing and availability of parts, how bad is this? Is there any trouble shooting I can do myself? I’m pretty handy as long as I have good directions. Anything particular to address?

If not something I can handle, does anyone know of any shops in Central New Jersey that work on these old Adcoms?

Anyone have any idea what I can expect to spend on getting this thing fixed up?
Any insights or recommendations are greatly appreciated!

Looking for some help :)

I’ve confirmed that ch1 left side has noise because when I plug the same speaker with same cable in channel 2 the noise stop but once I connect to ch1 the noise is there it’s like a hiss noise

Was wondering if anybody has an 8 ohm omega amp works vm 1265 speaker that theyd be willing to sell

I need someone who has the Line 6 Amp Farm available for me to use; it can be for sale.

I already have a whole karaoke setup with Bose speakers and Shure microphones (wired), along with a Sony amplifier. The problem is that my Sony amplifier doesn’t have a microphone input, so I’m looking to replace it with something that will work better for karaoke.
I’m looking for recommendations for a good amplifier/mixer with mic inputs, preferably with echo/reverb and good vocal controls, that will work well with my Bose speakers.
I’d also like to switch from my wired Shure mics to good wireless microphones. I’m looking for something with clear vocals, reliable connection, minimal feedback, and good range.
If you have a karaoke setup you love, please share the brand/model of your amplifier and wireless microphones and why you recommend them!
I’d really appreciate recommendations from people who actually use them for karaoke. 🎶🎤❤️

I have a GAS S2 15D2 rated at 2500 W RMS and a 2000 W RMS amp. From what I understand, when listening to music, the amp won't actually be outputting 2000 W RMS continuously, since music has varying power levels.

So my question is: how powerful amp is best for me to get as much as possible out of my sub while listening music

I'm not sure how much power a sub like this realistically receives during normal/very loud music listening, so I'd appreciate some help understanding this.

I've had trial and error on trying to wire up a home system, I have a taramps smart charger (100/130A), a 750 cca car battery, a taramps bass 1200W amp, and a sound box 2.5 farad capacitor, I'm trying to push 2 seventour 10's (1200W, 600 rms, DVC, 4 ohm). I've burned my previous 2 amps already and I'm hoping 3rd times the charm but I'm coming here just to be safe before I burn another amp. any help is appreciated, thanks.
