Vintage H. H. Scott Stereomaster 340 Tube MPX Receiver Tested. Needs TLC (B)
Thursday, January 1st, 2026






Scott Stereomaster 340 Receiver. Up for sale is a A rare used 1963 H. Scott Stereomaster 340 vacuum tube MPX receiver. All tubes were tested and they are good to N. The original four Amperex 7591 tubes test excellent at 8,500-9,250 umhos. Controls work but there is switching crackle in some. The unit is in excellent cosmetic shape with a few small marks that are shown in the images. The plastic tuning dial is missing. With the bottom cover off, everything inside looks original to the factory design. This unit does partially work but will need work to bring it back to factory spec. I have included a fairly hard-to-find owners manual and schematic for this unit. This is a highly sought after integrated tuner with great build quality. With some TLC this will make the centerpiece of a fantastic stereo system for someone looking to explore tube audio. The unit is very heavy and will be packed safely. I will pull some of the tubes and pack them in tube boxes.
