If you want to blend in tubes look at the Rogue RP-5 $3.5k new and see if the numbers match up with what you need. If you need balanced then look at the RP-7 used . YOu might catch people moving off the 7 up to the 9. Then you can start rolling tubes which is fun.
Rogue gots good customer service as well.
