These are the 3 classic Chinese tubes on the amp. The small tube in the front is Beijing 6J1 (1978) which is same as EF95/5654/6AK5. The smoked glass bottle tube is Shuguang 6P6P (1989) which is same as 6V6GT. The rectifier is Nanjing 5Z2P (1974) which is similar to 5Y3.

Description and specification of 6J1-J were attached within the box. A QC certificate was also provided and shown production date (May of 1980), inspection date (June of 1980), name of inspector, etc.
The factory is serious.

Peking electron tube factory is one of largest tube manufacturer in government base in China. The most of their tubes are for military use with fine quality. The factory was already closed in 1980s. The well-known Peking tubes including 6N4(12AX7), 6N3(5670), 6J1(EF95), 6P14(EL84), etc. are still being used and kept by audiophiles.

Cheers.

This time, we try to simplify the speaker outputs for this small amp as the space is very limited. The white binding post in the middle is 0 and shared by the both channels. There are 4 and 8 ohms for each channel.
