My 909,

After bypass the Quad Link now, better than before X 12.

Just try with your 405.2 and see the difference, simple and easy. better high tone, with more clean back ground.

weissenworth hing,

Difference between 405 and 405.2.....

Quoted from "Gramophone" 1983? issue:

"....So we now have the 405.2 with a new Quad designed protection circuit......... It should be stressed that there have been no changes in the amplifier or power supply .........."

Hope it helps.

Thanks hknative hing for your advice.
