Whh1234,
That is why I have to save up $$$ for more than 6 months before I can do it. Actually, it still exceeds my budget a bit.
I have, next to me, an original Sun Audio 2A3 from the local dealer. However, it is also modified using Tango Output Transformer (807 -- old model) and Jensen Ceramic Caps. The filtering is also BG 47uf + 47uf.
After running in for 10 hours, the difference between the two is not that significant already. As my 2A3 uses 6SL7 instead of 6SN7, the gain is definitely lower. I was still busy these days so I haven't much time to do a thorough A-B comparison. Will do that for sure after running in the 2A3 for around 100 hours.
Put it this way, DIYing saves a lot of money. I have heard that a new Sun Audio 2A3 now sells for over HK$ 15,000. Mine is, I think, HALF of that sum. |
