Nooby, at the very early stages of learning,
I've built this a couple of years ago and shelved it, but now I've got time on my hands it's back on the bench
I'm having trouble with hum and poor volume on the echo , I've got the oscillator running at 48k I don't know wether that's acceptable?
When I turn the echo pot up, it hums , I've put a 100 ohm resistor on the centre tap of the transformer for the heaters, but I don't really know if its the heaters or not.
I would be very grateful for any help, or suggestions, thankyou

I have refurbished a number of VOX echo and Meazzi machines.
Ensure the wires from the heads are twisted pairs and screened.

Here are a couple more; The first showing the front is a Meazzi on the previous post, the other two are the VOX from 1964 and the picture with the switches is the first ever prototype from VOX back in 1962.
All repaired, fully working again and gone back to their owners.

I also have a short tom, in good working order, the Meazzi is a project, today I have discovered there's only 38 v ac on the recording head, I think I've wired the oscillator coil wrong, there's only 8 vac on the erase , could that could be cause of a weak distorted signal on the tape?
