Random thoughts on Vintage Radio
A book by R.G Newlands ZL2AG
This book is a collection of previously published magazine articles contributed by George Newlands ZL2AG for the NZ Vintage Radio Society. Some of his writing has also been published worldwide and in the NZART Break In magazine.
Random Thoughts on Vintage Radio reflects his life-long fascination with servicing and restoring vintage radio receivers.
The book consists of 38 chapters (240 pages). It includes a diverse range of thoughts such as “Collecting –the disease we all share”, “Valve life and reliability”, “Servicing a Valve Chassis”, and “Disposal of a collection”, to name but a few.
There are numerous detailed technical notes accompanied with sketches and circuit diagrams written in his quirky and matter of fact style.
Recommended reading for vintage radio enthusiasts, or an ideal gift to someone you know who would appreciate a “real” book

Mag Loop Capacitor Starter Kit
This is a very easy to build variable capacitor with widely spaced plates. The configuration is a butterfly design, so that there are no sliding contacts to either side of the capacitor electrodes.
The capacitor stator plates are suspended on four M6 brass threaded rods. This makes direct connection to the ends of a robust loop conductor very practical. This very direct connection will keep the mag loop resistive losses to a minimum which is very important if building a transmitting loop.
The value of the capacitor in pico Farads (pF) can be adapted to a wide range of mag loop arrangements by adding or removing stator and rotor plates that are held on the threaded rods with M6 brass nuts.
The starter kit with 9 rotor plates and 20 stator plates will give a capacitance of about 12pF to 65pF and a voltage rating of 3.5kV.

Kit of Parts
The starter kit is supplied with 5 threaded rods that are 90mm long to take the full complement of 9 rotor plates and 20 stator plates, using the supplied M6 nuts as spacers.
Different plate spacing can be achieved by doubling up the nuts, or using longer tubular spacers and longer threaded rods if higher voltage ratings are sought. This will also reduce the capacitance in pF per plate set.
