Hey all, I have an old 70's amp/ Technic SU-v5. I want to play my Guitar through it, it has phono and tape input. I was wondering if its possible to get to play, use an RCA to 1/4 inch jack. I will be using a fender telecaster
Thanks,
Thanks,
Not likely. Guitar pickups need to be connect to high impedance input of 1Meg ohm or more. our RCA line in are going to be 50K-100K, much too low. They also likely won't have enough gain.
Some of the more knowledgeable guitar guys will fill you in on details of what you need to make it work.

Buy DI box or even better amp sim pedal. Something like this JOYO Technology sounds really nice and is rather cheap. Guitar connected directly to hifi amp would sound too flat.
Yes, you need a guitar preamp like this one which also includes guitar amp modelling. Input impedance is the required 1Meg ohm.

Connect it between the guitar and the tape input of your amplifier.

My first "guitar amp" was a Webcor tape recorder, with an internal 5x9" oval speaker. I am sure it sounded awful, but to me it was heaven.
Yes, your stereo receiver will play the guitar. WIll it be optimal? No. But if it sounds OK to you, then who are we to tell you not to use it?
I agree that some sort of guitar preamp would make it a lot better.

Add a splitter lead to ensure your guitar sound comes through both channels of your stereo amplifier. 404: Page Not Found - Scan.co.uk)

You'll get sound at useful volume in a home setting if you go through the phone input for sure. Line in not enough gain. But a di box as others have said will work better.
Mono jack plug to 2 x RCA plug splitter lead - example.

P.S. Do NOT use the phono input as it is frequency equalised for record player cartridges and will sound awful on guitar!

Buy a cheap ($20/25) distortion pedal at local GC or pawnshop or Craigslist or garage sale and use it as a buffer: Distortion on 0 , Volume on 10 , Tone set to Bright so it adds some "guitar EQ".
It will have the proper high input impedance and probably add a little grit and "guitar sound".
95% of simple distortion pedals are "an Op Amp plus a couple diodes" and meet the above requirements.
A simple alkaline battery is enough to power them, since you clearly are not an 8 hour a day 7 day a week rehearsing Musician or you would get a real amplifier and in practice will lastg months.
For occasional "hobby" use your pedal will be fine, last a lot, and eventually provide some Rock sound as needed.
The typical cheap Distortion pedal has this in its ADN, plus some bells and whistles:
Of course, make a single mono plug to two RCA adaptor, and use Aux inputs; the Phono one being both way too sensitive (will ugly distort all the time) and RIAA equalized (tons of muddy Bass, Zero treble).

I tried it
I took a 1/2 inch to 3.5mm adapter and plugged in a 3.5mm to red and white rca into the converter, I tried it in the phono input and the aux, and it sounded alright, it did, however, have a hum when I didn't strum the strings.

Have You tried mic or instrument cable instead of the flimsy parallel RCA cable ?
You have an impedance mismatch. Phono is usually 47k impedance and Aux 10K, but You need some high impedance stage like 100K. Try a DI box in between. You could also make a small pre-amp and put it inside the guitar.

There is - see my post number #4 - a cheap and effective solution!I guess you're right, is their no way to get the hum out?
Oh thanks, I found in my house a di box high to low impedance transformer. It's a VIB GDI - 1. The brand is vibe amplifications. Can I send pics on forms?
Yes, go ADVANCED under the reply box then attach your pics by clicking on the paperclip symbol at the top of the new window.Can I send pics on forms?
you say it 'hums' when your not touching the strings or strumming...that's common with single coil pickups they can behave like antennas and pick up noise.
