Transformers

the transformers for the +/- 170V and the filaments for EL509/EL519 are from a very nice net friend momo. It was originally from 梁氏. However, they are a bit over spec and the voltage are +/- 135V without loading and 23V for the filaments. This prompted me to work on the idea of 12 tubes....

However, the transformer is of very good qualities. I did plan of showing the transformer outside the case but worried about if it is not a good one and need to be replaced......
