Default Re: Building the 'Minimod' AM modulator-questions!

Just a reminder that the two coils for the Mini-Mod can still be obtained from Spectrum Communications, which is a small outfit - Tony Nailor and his wife Jean. You can also get the BF256 FET, the BC109, the LM386N-1 IC and no doubt most, if not all, of the other bits from them. From their website, as of 5th August, 2018 the prices were:

10mm 10K RF/IF COILS: Two are required – 90uH, type ‘90u0L’, listed at 80p each.
BF256 FET 50p each, BC109C 15p,
LM386N-1 £1.00.

P&P is £1.50.

When I buy stuff from Spectrum, I usually ring up and place the order with Jean, on 01305 262250 and pay by debit card so they don't have to stand PayPal or credit card charges.

Incidentally, some forum members may be aware that from 2004 Tony Nailor wrote an excellent long-running series in Practical Wireless entitled 'Doing it by Design' and 'Technical for the Terrified' which suddenly ceased about a year or so ago. I'd wondered why, and the reason is stated by Tony on his website. I mention that not for debate or comment, simply for information.

Hope that's helpful.
