And, oddly, there are now not one but two refurbished NYAL Futterman OTL 3’s for sale in the $6,000 to $7,000 range. You can wait for a decade before you see them show up. Get a pair and you are set for life. I’ve had mine for 40 years.
There are also two OTL1’s. The sellers asking are insane: $19,000 to $33,000. For amps that will need work.
