Vinod,

I'm sure some pictures would help. Also some detail of the transformer types

Iam adding 2 pics. The case is a steel Hammond make.

The transformer 374BX is again Hammond and can be looked up. Essentially
Primary - can be wired for both 120/240 V
Main Secondaries given below.
- 750V CT (175ma)
- 5V CT (3A)
- 6.3V CT (6A)

The choke 193J is 10H, 200mA.

The OPTs are UBT2 - US made. 5K primary to 4/8/16 Ohms. 110ma max primary current. Max output = 13 W

The power output of the amp should be around 5 to 7 W x 2 channels.

The coupling caps are Audiocap, filter caps are Mundorf and other caps from Nichicon. There is a CCS circuit on the anode of the D3a.
