Rising prices for studio quality R2R machines
Looks like the bargains have almost disappeared now. Prices for studio machines i.e. Studer, Sony APR, Telefunken, Otari etc have firmed considerably in the last 2 years. Whereas you could have bought a decent Sony APR 5000 machine for £500-800 then, you would be looking at £2k plus now. Same for Studer A807s which have almost doubled in asking price in this time.
I suspect that interest has been revived enough to increase demand. With only a limited supply of machines (most were put in skips in the 80s and 90s as studios went digital), it is just the old fashioned law of supply and demand.
