Just finished building the Stereomour for 45 tubes. No smoke and all voltages measured good.
Using a pair of Radiotron UX-245 globe tubes and my Klipsch KLF-20 speakers (100 dB/W/m). Only need to run at half volume to fill the room with smooth, lush, and 3D sound. While in the build process, I upgraded the parafeed caps to 4.7 uF Mundorf Supreme's, replaced the pot with an Alps Velvet, and the coupling caps with Sonicraft's.
Just have to thank the Bottlehead folks for a great kit. The manual was well written and easy to follow. Brought me back to my youth building Heathkits.
Looking forward to many years of beautiful music.
