Looking for info on Knight amplifier

Greetings everyone,

Hopefully this is the right forum for this. I purchased an unknown Knight amplifier years ago and never finished the project. I'm looking to complete it now, however I can't locate a schematic for it.

On the face plate it says "Knight 32w. Stereo Amplifier". The amp was purchased with no tubes, however someone wrote the correct (hopefully) tube numbers by each socket. The tube compliment is as follows: (5) 12AX7, (1) 7025, (1) 5AR4 rectifier, and (4) 7189 outputs. I know that the 5AR4 rectifier tube is too tall to fit in the enclosure, so I assume it originally used a solid state setup. Its a gray face plate and brown wrinkle on the enclosure color combo. If I can give you any other information, I'd be more than happy to.

Does anyone have any idea on what model this could be and where I could go to obtain a schematic?

Thanks for any help,
Dan

Put up some pics of what you have: enclosure, faceplate, rear configuration, etc. Allied made a lot of Knight-Kit models. Without a model number we will need to see what she looks like.

Enjoy,

Is it a KN-3032 perhaps? Some 5AR4 are taller than others-especially the re-numbered Russian types. A real 5AR4/GZ34 is barely taller than most 6V6 tubes and not much taller than the 7189 iirc.
 
Like this (sorry photo is crap)... 3" from the top to the base excluding pins.

Haha, found a picture of it on a forum that I posted on when I was about 16.

Hmm, maybe the 5AR4 that I set in the socket years ago was one of the Russian types.....

Thanks for all the help!

The model number on Knight tube amps is located on the data plate on the rear of the unit where it lists the voltage and current.
 
I think that I have that same amp (at least mine looks very similar). :scratch2:

I'll look tonight for the model number if you don't find it sooner. :thmbsp:
 
Knightkits often didn't have the model number or catalog number at all.

Spend some time at alliedcatalogs.com (I'd suggest starting with the 1960 catalog - could be a few years later).
 
That's it! Looks like it, same tube compliment, same chassis layout, etc. Thanks!

Just looked up the 1962 Catalog.....it's in there!

Now, if I could just find a schematic. Do you guys have any sources for schematics for old Hi-Fi equipment?

Thank you for everything,
Dan
 
This looks like it (in case the OP hasn't found it at www.alliedcatalogs.com yet):

This brings back memories... spending evenings sitting with my dad at his workbench as he built one of these. He gave me my first soldering lessons and I've been a soldering fumes addict ever since. He built his entire system from Knight kits...the shopping trips to buy the kits were always a couple of hours as he checked out everything and chatted with the salesman... great memories.
 
yeesh, that looks like the same size cabinet as my KP-50 preamp. If it is, that has got to be one tightly packed amplifier.

A great story. Many of us would envy your experience. Thanks for sharing.
 
Dandy, thanks for the kind words. I'm retired now (where did the years go?) from a career in electronics, so it just made sense that DIY audio stuff would be a great hobby. I have a 20 yr. old grandson who enjoys his time with grandpa at the workbench... I've taught him how to solder and basic meter use.
This summer, I'll supervise as he builds his 1st project, a tube amp for his bass guitar.

Oh yeah, he wants to inherit all of grandpa's stuff...

Many years ago. Maybe 1958-1959?
It was ok. Is this the one that can't decide what the channels are named?

Inputs are called Left or Right.
Front panel switches are called A or B
Output is called Channel 1 or 2.

Sort of an idiosynchrosy of this one.
I built it and kept it for several years until I could afford a Fisher KX-100. This Knight I gave to a friend around my age and he nearly had a heart attack.
I remember the Knight as working fine but always thought better would come along. It came along when I started working as an apprentice and could afford better.
I don't have a photo of the Knight but did take a photo of the Fisher. Photo is in my photo albums on this site.

What a lucky man you are. I'm retiring next March and have a Godson that wants to learn this stuff, but he lives 8 hours away in Dallas TX. I bet you two have a blast. This post made my day.:thmbsp:
