Very very rare 71A PP stereo tube amplifier, using Kenyon T-108 output transformer. Kenyon T-108 was made in 30s year, which is same era with Western electric. It use LUXMAN MQ-60 chassis.

71A tube is excellent tube for audio, it is same as 101D, 102D , which is very musical and beautiful sound, but it has low output power so it is very difficult to make an power amplifier with 71A as output tube. An single end 71A tube can procedure max 0.8W, this amplifier is push pull working in class A1, give output 2.5W , good enough for driving speaker higher than 95db.
Sound is perfect, very beautiful and detail with rich sound. It is really amazing sound with such small output. Kenyon transformer is really good. In secondary, there is 200ohm and 600ohm tab so you can use this as preamp, just add output RCA.
Input volt is 100-117V, it is best if 110V.
This amp can be changed to 45 tube amp, just make some small modification, if you want to change to 45 tube let me know.
Tubes using in this amp is very popular and easily to find. Prestage tube is EF86, driving tube is 6DJ8 (6AQ8, 6DT8), rectifier tube is 6AX5.
I dont include 71A tube, but include another tubes.
