FISHER KX-90 seek Sams!

Hi all,

Might anyone have some SAMS for a FISHER KX-90 Integrated Tube Amp ?
I checked with my usual source for lit. and nothing turned up.
The FISHER KX-90 has four 7189's and five 12AX7's.
I sure would appreciate any information for this unit. Thanks.

Regards,
Tom aka SixCats!

The "K" indicates a kit - so it won't be in Sams. But it's probably the same as one of the X-100 or 101 models... I have the Sams folder for the first version of the X-101 - same tubes, five knobs in two rows, two slide switches. Transformer part numbers would probably nail it...
 
I have the assembly manual

I am actually in the process of recapping my KX-90 right now (only the can caps left to replace). I have the StrataKit Assembly Manual for it, which includes the schematic.

Do you need a copy of the schematic and the parts list?
 
Hi guys,

Thank you for responding to my thread. Tom, I did infact try to go the same route you suggested (i.e. X-100) but found that the X-100 tube were not the same as the KX-90's 7189's so, I'm thinking there must be some major differences in the units make up and...this is the reason for my post.

Joenielsen...once you get your KX-90 back together, I'm betting your going to LOVE it! Prior to my KX-90 developing it's problem (most likely due to being all original/old caps etc.) it's sound was EXCELLENT! In fact, I liked it better than my FISHER 400 Tube Receiver (which is no slouch!)
Ooooh, God yes, I would very much appreciate a copy of the schematic and parts list! Thanks so much for you kind offer.

Sixcats!,

PM me with your e-mail address and I"ll try to scan and e-mail you those things tonight.

What's the problem with your KX-90? I agree, it is a very nice sounding amplifier. Mine was working fine when I got it (just had to put some new tubes in it), but I am recapping it because I plan to use it long term. I am taking it slow and testing it after I replace each cap (or a couple at a time) just to make sure everything goes smoothly. It has been a very easy recap so far, but the hardest part will be bypassing the can caps underneath the chassis (between the 3 cans, there are 7 large electrolytic caps that I have to find space for underneath). I only have the 2 and 4 section caps left at this point.

I have a fully restored Fisher 400 as well, and I thought the KX-90 -- even in unrestored condition -- sounded better. Very good synergy with my Bozak B-302s, although not as good with my Wharfedale W-70s (in my opinion, anyway). I think it is the output tubes (7189/6bq5) that make the difference, because I also thought my Stromberg-Carlson ASR-433 sounded better than the Fisher 400.

I am actually planning to use the KX-90 in my office as a headphone amplifier when I am finished. It really sounds great with headphones.
