Years ago I had some JBL L36's very similar to yours. I powered them with a Marantz 2220B receiver. It was very well made, old Marantz prior to Superscope, with an oversized transformer. It only output 20 wpc but sounded wonderful.
I bet you could get a 2220, 2230, etc pretty affordable on A'gon or Ebay.
The Virtue sounds like a great match, too.
