Getting back into valve technology after many years of doing other things and plan to retore the HMV Little Nipper 62-52 I was given many years ago but need a schematic. I note this has been requested by others so I am hoping someone can help

Welcome to the site.

You can download the schematic from here:

http://www.kevinchant.com/hmv2.html.

Otherwise use Control Panel to unhide your email address and I'll send you the schematic and notes.

Also, you might get some useful resto tips here:

Beware of the screen resistors feeding V1, V2. There were a heap of these with the same (basically) circuit, however the Accounts department seems to have been involved?

On some this was two 1Watt 22K in parallel. On others it was a single 10K that appears to be 1 Watt.

More than 10mA through 10K is more than 1Watt and they often cook. Use a 2 Watt or parallel two 22K's.

There are a lot of these "Nippers" around & I have dealt with quite a few.....even have one.

Thanks for the advice. Could not find the 62-52 on Kevin's site so have unhidden my email address so you can email me the circuit.
