Jadis OR bias value for Mullard RL34 and KT88 help

Thanks much Mattzack2,
Based on physical dimension I believe you are talking about the internal fuses which, I was told by Jadis, should be slow blow 0.5A and not 5A.
The one I need is located next to the power cable, easy to reach by unscrewing a fuse holder and about 1-1/2X longer than the other one. I believe this should be fast-acting but I don't know more.
Thank you so much and I hope I'm making sense since English is not my mother's tongue.

The fuse ratings are typically on the fuse cover, and then again on the fuse. If all else fails see if you can download a users manual from Jadis. The other sources are probably commercial and would want a fee. Joe (Trelja might pop bback in to help you also. If not spontaneous start a new post.

Thanks Doctor,
The fuse cover does not have any information and the fuse itself is very difficult to read, I've tried Jadis and their US distributor with no success and my last hope is Joe who has been the "fountain of all knowledge" in terms of audio for me, a great guy

My apologies for the late reply, just arrived back from our summer vacation.

My JOR uses a 4A/250V fast blow fuse. Personally, I feel a slow blow fuse is always the better way to go in this application.

Doctor, can you let me know your e-mail address, please?

Sure Joe, you know what I have a rarely used one that I don't need to protect so carefully, I will tell you here try stmechanic1@comcast.net I can only access it occasionally so forgive me for a slight delay. Once there I will update you on my current addy. Thanks for asking it has been a while my old friend!
