Line Stage for Mikael SE KT88

cjctan · 2nd June 2009, 06:54 AM

Hi All,

I will start building Glenn's version of Mikael SE KT88 amp when I receive my custom-made "irons". While waiting for them, I would like to hear some views from other users of the Mikael and its variants on using a line stage for this amp.......

I foresee that an external line stage will be needed as I have a few sources that I would like to connect to this amp....

May I know which of the following options would be the preferred choice for this amp?

a. Passive, mechanical selector (switches,relays and etc)
b. Mechanical selector followed by Buffer Stage
c. Mechanical selector followed by Gain Stage
d. Others

I would appreciate any views/comments/advices on this issue.

Thank you

A. The Mikael amp has PLENTY of gain on its own. Is there any reason you can't just drill a few more holes on the back of the amp and wire in a selector switch?

Hi sorenj07,

I can do what you have mentioned and make a multiple inputs SE amp if no extra gain is needed.

Thanks for your input.
