I love the old stuff. I have built up a little Akai 70's system and it cost me bugger all.
The tuner amp I paid $90 for and had to get it repaired for about $300, still a bargain.
The tape deck I paid $150 for, sounds fantastic.
The turn table belonged to my father and I replaced the drive belt and cartridge, also added a platter weight.
I'm currently playing with an Akai reel to reel tape deck that someone gave me.
You don't have to spend a fortune to have some fun.
