Ceramic cartridge to line level input circuit

Rock-ola is still in business, you can contact them:

If you want to directly connect the output of the ceramic pickup to a line level input of a different amplifier (meaning not to the internal tube amplifier), I would recommend a FET source follower (3 components plus battery). The PU is mono, isn't it?

It's a 78 rpm shellac juke box. . Don't believe stereo were available.

A generic no name amp?
Or a shop purchased item with a brand name and model number?
Do it yourself amp?
How much output?
Or a generic pre amp circuit? As an all in one level matching device?

Female or not, you are being mysterious and confused.
And ceramic cartridges went out of fashion long back.
Also, their output at times is enough for some amps. No need for a pre amp.

You don't know what you are taking about! Your the only one confused here and there is no mystery. Read the entire thread. A ceramic cartridge needs an input impedance in the meg ohm range or you will lose bass response. Line level inputs are in the kilo ohm range. Why I want to use a ceramic cartridge is irrelevant and frankly none of you business though I did explain it earlier in the thread. Read the entire thread before you make anymore stupid comments. So you want more specifics re what I will plug this preamp into:

1. Technics Stereo Integrated Amplifier SU-V78
2. Marantz Receiver SR-6011
3. 2 x 4 MiniDSP https://www.minidsp.com/products/minidspkits/2-x-in-4-x-out

Now that you know the specifics tell me how you can help me now that you couldn't do before

Prickly, aren't we?
What was so secret about this information?

Wait for the more experienced members to give their opinion, in about 12 hours...I will also tell something later.

No secret just wasn't necessary idiot

See posts 7 and 9
And stop being rude.
The Marantz is complex, your DSP is a boutique item, more show than work.
Enjoy.

I'd prefer posts #13 and #26, as those are designed for ceramic cartridges. In fact any of the circuits in this thread will do, except those of posts #7 and #9.

Due to manufacturing differences in those amps, they all likely have DIFFERENT analog line level loadings, and sensitivities.
For instance, one might have a 22K input load, another could have 10K.
Another might have 100K.
So with that stated, unless a service manual can weed out and determine those differences, it's almost impossible to design a single adapter that works the SAME way for all of them.
Aim for 150mV output level buffer amp and hope for the best.

Then it's equally impossible to design a tuner or a CD player that works with all of them.

Post #13 is the way to go, period. You discovered it yourself, here I confirm it.

As mentioned above, you have found the circuit you need. Solution to the problem is posted. This thread will take a pause for tempers to cool.
