I don't know if that is the right term but my data sheet says my device is in a HO-3 case can anybody tell me where to get some insulators? i don't want my case at -35V
You don't mean T0-3? (not HO). This can is rather common. Look for insulating details, heatsinks etc. at your favourite dealer.
I took apart a JVC integrated amp one time and there was no insulator on the chip. I can't remember if the heat sink was isolated or not. If you have the pinout make sure the case is hot. If so, try to find one salvage in a repair shop maybe, or perhaps find a sheet of mica and cut your own. Good Luck🙁
The case of the device is not hot, Just apply heatsink compound to the metal surface and bolt to heatsink.

It had insulators on it when i pulled them out of the amp they were in (everything but them was fried) but you say the case is not connected to + or - ?
The cases on most STK devices are not hot. They are bolted directly to the heatsink. (No Insulator)
These devices have been used by JVC, Pioneer, Yamaha and Sanyo ( who also makes a lot of these devices)
I will check on the pinout early next week and let you know for sure.

If it turns out that the heat spreader on the module IS tied to a pin as compared to electrically isolated, get a piece of Kapton film (preferably Kapton MT or similar) that's a mil or two thick, trim to fit (leaving extra along all edges), coat both sides of it properly with a good thermal compound, and use it as the electrical insulator.
Kapton is thermally conductive (0.37 W/m for the MT type) while acting as a HV elctrical insulator (5KV+ per mil dielectric strength).
