Hello: I am looking for advice. A few years back, my (then) 13-year old son bought me an old Fisher rack/shelf stereo from a thrift store for Mother’s Day - mostly for the turntable. He did some minor work on it, replaced the needle, etc. and I have used it regularly for about 7 years. Works fine for my needs. However, the speakers are huge - really heavy and bulky. I was hoping I could buy some new smaller speakers to replace the giant ones but I am not sure if that will work and the info online is confusing. So, I thought I would ask the experts. Can I use new speakers on a 1980s era Fisher CA-77 receiver? I understand that I would get much better sound from a new system, but since my kid (who is now in college) got this for me, I would like to keep it. Thanks for any advice.
