Just reached home and inspected the kit from under side....its D101 .....and shocked to find that it was already repaired
... as youcan see from the pic at the end...
I have my digital volt meter lcd broken last week so for now I think I should change the module and kit both...and keep this kit for emergency when suddenly if other kit breaks...
However I already tried removing these wires and connecting ups to battery without AC supply and noise from transformer was gone as if normal operation... but connecting biasing wires to kit again gives too much noise...
please suggest if this combination is fine or there is better transistor to replace 150M?
2 new plates with IRFP 150 M and Imran & Co. D-104 kit
Below part looks repaired
