Going by my first real set up , around 1979, which was a HHic100s and 2x15 speakers , which I think I paid about £200 for second hand at the time, I’d say the Peavey rig would be between £400- £500 🙂
Thanks jazzj, I’m still looking but there’s none near me at the moment, there’s a few newer ones but I like the older ones, there’s one on eBay I quite like the look of but it’s too far 🙂
