Subject: [BITX20] Components from Rapid Electronics

Finally here's a full list of what I can order for you from Rapid
Electronics Prices are the Rapid prices,
i.e. no profit for G0UPL? :-(?? Postage is the price of a UK 1st class stamp
for UK orders (?0.28). Other countries will be extra at cost.

You must tell me your orders by this Wednesday at 13:00 UK time (12:00 GMT).
I will order on Wednesday from Rapid, receive the components on Thursday,
and send them out to you on Thursday. UK orders should receive them on
Friday, ready for the weekend's homebrewing! Don't send any money yet, just
tell me what you want and then wait until Wednesday when I have placed the
order at Rapid: it might become slightly cheaper still if we go over other
quantity pricing thresholds.

You can pay me by any of the following methods:

1. Paypal (preferred) to my email address. Anyone can use a credit card to
pay me this way, without needing to be a PayPal member, see
.

2. UK cheque or postal order

3. Cash: British Pounds, or if you like approximate equivalent amounts in US
Dollar or Euro. Not other currencies please, I am a homebrewer not a bank, I
can't handle Mauritanian Ouguiya or Azerbaijanian Manat.

If you are going to pay by 2 or 3 above, then I will send you my postal
address via email.

Rapid do not stock 2N2218 driver transistors, nor are they at Farnell
However I have managed to find a different source
for supply of 2N2219A which is like the 2N2218 but has better gain
specification. I'm sure it will be suitable.

So here's the prices and description: feel free to take all items or only
those you think you need. To keep it simple, transistors will be in a set of
25 BC547B, and diodes in a set of 15 1N4148. This leaves a couple of
transistors and diodes left over for later modifications! If there's
anything else you need particularly then let me know. Varying the quantity
is fine too, e.g. take two IRF510's so you have a spare if you are worried
about frying them, or if you want to play with push-pull for higher output
power.

Prices are in UK pounds inclusive of VAT (sales tax).

?3.58? Qty 10 of 10.000 MHz crystals, HC49 style
?0.59? Qty 25 of BC547B transistors
?0.70? 2N2219A driver transistor
?1.53? IRF510 MOSFET
?0.19? Qty 15 of 1N4148 diodes
?0.07? 36V Zener diode
?0.05? 9.1V Zener diode
?0.05? 5.6V Zener diode
?0.29? LM386N-1 Audio Amp IC (correct variety)
?1.88? Qty 5 of 2-22pF trimmer capacitor
?0.71? Miniature tuning capacitor*

?9.92? total, if you wanted everything and including ?0.28 UK postage.

* NOTE: The tuning capacitor is one of the miniature kind as used in
portable radios. Size is 20.2 x 20.2 x 10.8mm. Control shaft is 6.6mm
diameter tapped with 2.6mm thread. Panel mounting is via twwo 2.6mm tapped
screws next to the control shaft. Capacitance: AM section 3.0 - 141.6pF,
Oscillator section 4.0 - 59.2pF. So in parallel you'd have 200pF which is
less than Farhan's design for 350pF. It might therefore be necessary to
alter the VFO coil to get the required tuning range.
