The JoLida 502B was my intro to tubes thanks to John at Community Audio in Germantown PA. Had that unit for 10 years and put a lot of hours on it. It was reliable, robust and benefitted from tube rolling, HiFi Tuning Fuses and especially the very affordable JoLida Maryland factory upgrade. I liked it best with KT88s vs 6550s. I very much enjoyed that amp and only moved away from it to get some higher power mono blocks to drive Totem Forests. Hope you can find somewhere close by to audition the JoLida or other tube products you might be considering.
