For under $1K it will be difficult to find something equal to your Curcio 70 that won't require a refurbishing in the next 4-5 years (or sooner).
You might considering paying a tech to redo your 70. What does it need other than lytics?
You could purchase a recently rebuilt 70 (the normal looking ones go for around $600) and sell yours as an offset.
This would leave you plenty left over for better tubes, a bigger Turkey...
If you just want a change look into used Quicksilver mono block amps (many come up for under $1K/pair), but depending upon age/condition they may soon require new caps as well.
