Hi Ampdog and All. I am looking for a simple PP circuit using KT88s. I have spent a lot of time researching this, but have failed to find ?just the right one?. Years ago Elektor published a nice looking amp design using a pair of EL156 tubes. I can possibly modify this design. Elektor also published an interesting PPP design using KT88s. It is definitely more complex though. Van der Veen uses EL34s almost exclusively. Maybe I will re-purpose one of those designs. Any advice well received. Thank you.
