Likewise, along with transistors and ICs if they need to be ordered in larger quantities than needed.

Perhaps someone could point out this thread to Spectrum and suggest they offer the coils in packs of 2 for a few weeks?

Thanks Peter, the Mini Mod PCB arrived this morning, Looks good.

I've ordered my 5 pack of coils from Spectrum via eBay, but in hindsight wished I'd just ordered two or four directly from their friendly website.

I've ordered my favourite project box, switch, LED lens and PP3 battery drawer from CPC, but then discovered they no longer stock the LM386. Spectrum do stock that IC and will happily supply the resistors in the small quantities required.

I might keep two coils up my sleeve for a future build but will happily pass the 5th one on.

Kind Regards,

SR

I have contacted Spectrum and gave him a heads up about the number of boards sold and on order. He tells me that he has sold quite a few coils recently and has received enquiries about the transistors and IC.
He says he is thinking of offering a kit of these parts on e-bay to accompany the board offer.

I have just had a message from Spectrum. They have put together a kit of parts to go with these boards for the Minimod project:

https://www.ebay.co.uk/itm/Minimod-p...YAAOSwDJ5gPo5d

I have no commercial association with spectrum.

Superb.

That's way less than the 6.60 (inc postage) I paid for five coils the other day

Anyone want to buy five coils??

Steve.

Wow! It's ended up on ebay - sort of! Really good to see so many people are still making this, and thanks to Peter for getting the boards made. Good idea getting Spectrum to put together the mini kit of parts.

Glad to see the Q1 BF256 and R2 3.3k changes have been made on the circuit diagram (previously 2N3819 and 10k). For anyone referring to the original article (below) I also hope the substitution for the BC109 doesn't cause confusion, and although it is easily substituted, many substitutes have different CBE pin-outs - sometimes even those of the same type.

Anyway good to see it living on after very nearly 10 years!

Regards,

Ian

PS: Another minor change; C12 is 680nF and can be substituted with 470nF which is a little easier to source. This might give a very slight reduction in bass response - theoretically anyway!

The Spectrum kit of parts substitutes a BC548 for the BC109.

I used a BC549, which is a low noise version of the 548 and has the same pinout, in my MiniMod and it worked very well.

I attach a close up photo showing the orientation on the board.

Hi Peter - I'm very late on this! Any possibility of adding a couple of boards for me to the list?
Cheers

Hi Andy, I am really sorry but all boards for both batches have been allocated.
The first batch has been posted to members and the second is on its way from JLCPCB

I did say that I did not intend doing a third batch but this whole project has taken on a life of its own, especially now spectrum are offering a kit of components.

So I will see what happens, if I get enough requests I may be persuaded to run a third batch......
