Hello, I am Russell. I recently retrieved my first ever tranny (was second hand) from my 'I'll get to it someday' bin. Sold by HG Palmer, no brand name on the outside, but has 'KGH TP 100 Pat # 145360 on the circuit board & VCZ33 on the speaker, has a 'leather' covering, measures 17cm long by 11 cm high by 6 cm deep, tuning knob on the Right hand face & on/off/volume knob on the Left side. It 'scratches' when I connect the battery, where do I go to begin diagnosis please, I have a moderate knowledge of reading resistance, voltage, etc on a multi-meter. Any advice will be much appreciated. Cheers.

I have just found out that the 'KGH' may refer to 'KGH Titan', an Aust. electronics company who produced radios in the mid 20th century??

Yes, KHG was owned by Keith G Harris. KGH history here:

Details of the TP-100 here:

As to where to start, I would strongly suggest learning the principles and repair techniques. Suggested books:
