DIY Compactron SET Part 4

I finally got the Compactron front plate from the wonderful FrontPanel Express. The plan is to use this design on all my gear for the Jubilees. Then this gear will fit into the 5ft ham radio rack I am having powder coated soon. Call it an ode to ham radio. What amplifier should we build for the LF? The Jubilee has an active crossover so I need LF and HF amplifiers. The 6HJ5 compactron is for the HF. The jubilee HF is 110db1w1m and the LF is 107db1w1m on the LF.
