advice on a poweramp from a stereo system

[Model 6 Matt]

Hey all, ive been given a full setup to play records and radio with a preamp and power amp, turntable etc

all toshiba, looks very high quality

there is a nice big power amp, fully working, would i be able to use this with a guitar preamp like a tonelab se or line 6 thing etc? i havent had a look at the back inputs yet but my guess is yes, but its solid state but im sure it'll work fine. any reason why i couldnt?

Oh and it comes with 2 massive speaker bins, ok so their prob for hi fi, but with each speaker box having a 12 inch woofer (i think) and a 6 inch tweeter (i think), they sound massive! Ok with guitar or not?? They are supposed to be really good as advised by privious owner.

Move forward with GREAT CAUTION. Regular stereo speakers sometimes have problems with this type of signal and often get damaged. It can work though. Keep the levels low to start, and if you get ANY feedback, back the level off.

But the poweramp should be fine, even if in the future i replace the speakers to guitar ones??

Match impedence (ohms) from the cabinet to the amp in the future.
Do you have a model #? Old tube amps are ok. You may not have an ideal Solid state amp as it isn't "voiced" for guitar-amp like performance, but it will work if you use the right pre-amp until you get a "real" amp.
I don't think you are going to like the sound through home stereo speakers.

My second rig was a Teisco-like thing with a Fisher home stereo + speakers with a Dallas Arbiter Wah-Face. Truly excruciating tone.

Well im actually downsizing from a good tube combo to this setup as it wont be used as much really and if i wanna play i guess i'll have the option to do so. This thing is also going to be my record and cd player and radio so i guess the guitar thing is just a bonus.

might try it today with my old Zoom G1 and see if its likely to even work, tone can come later on.

Thanks all

more info welcome!

Ok, her is a quick 5 min drawing in paint of what i want do with the power amp setup.

Basicly from guitar to moddelling unit of some sort, then stereo cables out to the preamp of the hi-fi system which will allow me to add and reduce unwanted treble and bass (so kinda like an extra global EQ) and it also has a volume control which i hope will allow me to reduce unwanted clipping from either the moddeling unit or preamp itself, then go into the power amp from the hi fi (can run 4, 8 or 16 ohm) into the hi fi cabs for now (15 inch woofer or speaker of somesort, and very small tweeter which i may disconnect if i dont need in case it blows). May be able to run a normal guitar speaker cab into it but its not 1/4 jacks, its like wires to red and black so would make it a bit (but not very) harder to transport.

Basicly this is going to be a practice rig until i save up for the amp i want, and for the amount of time i'll be playing through it, it'll do me just fine i think, plus it'll play my records and cd's if i want it to by conecting the turntable and possibly a cd player.

Let me know if this is prone to failing in regards to sound, not tone!

Thanks

IMO it should work fine. However, the results might not sound as good as expected. The preamp should not care much about what the input is. as long as the tonelab has a headphones out (which I think it has) and you are using that as the input to the preamp. I wouldn't try connecting the line outs into the preamp.
Since you already are planning on changing the speakers, you are in the right direction. Hope you are considering the fact that guitar speakers are either 12", 10". PA speakers come in various sizes like 5.5". Also, the speaker cab size, material, etc. play an important role in the overall cab sound. Notice how all guitar cabs are constructed very different from PA speaker systems.

If its a great deal, get it. but, I dont think whatever changes you make is gonna make it a keeper. good luck!
