I have a question [raises hand]
how can you make(using LND150's) a shared-cathode stage like a superbass?

Only as part of complete devices.

I don't see problems. Only careful selection of the values in source network (& maybe biasing of this network).

but in what point i can do the "shared cathode" thing? between the diode and Rk?

Let us know when you start selling them, I'll be sure to add some links on the site and on my personal blog.  Plus I might buy one...

Some time ago I found very interesting MOSFETS IXTP01N100D.
http://ixapps.ixys.com/DataSheet/DS98809C%28IXTP-U-Y01N100D%29.pdf
1kV of the drain voltage, 25W power dissipation. That allows to use them with standard transformers for tube amplifiers.
I already received ten of them from arrow electronics.
Now I'm waiting for the ordered transformer http://www.classictone.net/40-18045.pdf to start testing.

Hi Mike,

Would these be suitable transformers for your 5W FET amp?

Dear All,

I want to build 90W PA version , but I have a huge problem with output transformer. Plase could somebody provide me some more information about it? Link on internet where it could be bought also can be usefull. Does it someone tried to build it with EI core and could provide parameters for 90W version?  Which type of tpk-190, exactly could be used for rewinding ? Thank you in advance, Igor

I think there is no way around winding the transformer for yourself. I built the 40 W version of it, and it is quite big with the windings and all. Just be careful to get a big enough core. All of the data is on the KMG site, I believe.
