Thank you D S D L, vintage hifi product is hard to find and repair, I also prefer to new unit, I used to try a domestic DIY brand valve amp, at 1000GBP range, not ideal match even not stable but easy to repair,lol~ I am a new audio enthusiast, There must be some good DIY unit, if I found some will let you know.
Regards,
Mawen
