Technical enquiries
We regret technical enquiries cannot be answered over the

Projects and circuits
All reasonable precautions are taken to ensure that the advice and
data given to readers is reliable. We cannot, however, guarantee
it and we cannot accept legal responsibility for it.
A number of projects and circuits published in Practical Electronics
employ voltages that can be lethal. You should not build, test,
modify or renovate any item of mains-powered equipment unless
you fully understand the safety aspects involved and you use an
RCD (GFCI) adaptor.
Component supplies
We do not supply electronic components or kits for building the
projects featured, these can be supplied by advertisers. We
advise readers to check that all parts are still available before
commencing any project in a back-dated issue.
Advertisements
Although the proprietors and staff of Practical Electronics take
reasonable precautions to protect the interests of readers by
ensuring as far as practicable that advertisements are bona fide
the magazine and its publishers cannot give any undertakings
in respect of statements or claims made by advertisers, whether
these advertisements are printed as part of the magazine, or in
inserts. The Publishers regret that under no circumstances will
the magazine accept liability for non-receipt of goods ordered, or
for late delivery, or for faults in manufacture.

Editorial
Looking forward to 2021
Where to begin with the year 2020? It has certainly been a year
we’ll never forget: lockdowns, endless statistics, economic
uncertainty and sickness. While it’s no antidote to a pandemic, I
do hope Practical Electronics has provided a welcome distraction
from some very serious problems. With luck, and a huge amount
of brilliant work from dedicated researchers, 2021 may well bring
a vaccine and the chance to put the virus behind us.
In the meantime, I hope you enjoy this month’s Practical
Electronics, which marks the very welcome return of PE/EPE
stalwart Mike Tooley. He is starting a new series – KickStart –
which aims to cover a wide range of topics with useful down-toearth advice, tips and hints.
For those of you who enjoy building Hi-Fi with valves we have
a special treat in the shape of the Nutube Miniature Valve Stereo
Preamplifier. This is based around a fascinating new low-voltage
thermionic valve technology that we hope to use again in PE.
Thank you, PE writers!
Practical Electronics stands or falls with the quality of its writing.
I always end a year with a thank you to our contributors. They
work very hard every month to bring you high-quality, original
content. So, in no particular order – a great big ‘well done and
thank you’ to Alan Winstanley, Mike Tooley, Ian Bell, Mark
Nelson, Mike Hibbett, Clive ‘Max’ Maxfield, Phil Boyce, Julian
Edgar, Barry Fox and Jake Rothman. Just as important are the
‘back office boys’, Stewart Kearn, (again) Alan Winstanley and
Kris Thain, who keep the shop and website ticking over.
Extra special Christmas present?
Even – or perhaps especially – a socially distanced holiday
season still comes with the unavoidable ‘What would you like
for Christmas?’. For you though, lucky reader, the answer is easy
– ‘I just want a subscription to my favourite magazine.’ You can
choose paper or online, and as a subscriber you can be sure that
you will never miss a copy.
From all of us at Practical Electronics, thank you for your support
over 2020, have a very happy Christmas and a healthy 2021!
