Inexpensive integrated tube amp recommendations?

Second vote for the SP-3. It was my first foray into tubes and is a excellent performer. It listed for about $1200.00 and can be had used for under $500.00. The stock tubes aren't bad, but it can be improved with NOS tubes.

It has some drawbacks. No remote and only two inputs. If you can live with that, you won't be disappointed.

Audio Space AS-3i might go for around your figure used.

Point-to-point, three inputs, the output power you want plus the ability to switch to triode mode from the front panel.

The Jolida JD-707A is a very musical 40wpc integrated, but it's around $1200 I think. If you can find one here on Audiogon, it would be worth considering. Other amps in the line that you might consider are the 102B (25wpc) for $650 or the 202A (60wpc) for $850.

Used Cayin A50T should be available or around or just over $800.
