If your question is if you can cut a big sheet into pieces, the answer is yes.
If you need them for a big class A amp I would look for Silpad 2000 or mica, which have a smaller thermal resistance.

Thanks for replay Netlist!
Does anybody know where I can buy Mica To-247 in Germany.
Only way is that they have OnLine shop or Email contact, no phone because i dont speak german.

Thanks for a kind offer Posthorn.
I did contacted Fisher once about heatsinks but they told me that they don't sell to private persons.I found some insulators at Wieser-Electronics for Large Japanese type(Sanken ) transistors and was about to order them but if you wish to do this favor to me then we can discuss this privately.

Hi,

if necessary, I can give you a phone-number of a dutch company that sells TO-247 insulators, in Aluminium-oxide. They are more expensive than Schuro (1,15 each).
