I’m thinking of building three VCO’s, but l can’t find a supplier in England who has the CEM3340 chip, all that l can find is a supplier in Europe who say that the AS3340 chip is a replacement for the CEM3340 chip. Do you know of a supplier in the UK who has the CEM3340 chip, l have looked on eBay and several other websites without luck, many thanks. ---

there is the link on the web page of Sam for this project 😀 > **[Curtis CEM3340 IC – Reissued VCO Chip – Thonk – DIY Synthesizer Kits &...](https://www.thonk.co.uk/shop/curtis-cem3340-ic-vco-chip/)** but a AS3340 is also good and more cheap ---

> **[Oscillators – Electric Druid](https://electricdruid.net/product-category/oscillators/)** Electric Druid have CEM3340s and others still - they’re UK based but seem to have been posting from portugal recently (I swear they didn’t before lockdown?). Anyway, postage doesn’t take too long still, think my orders from there usually take about a week EDIT: just realised these are twice the price of the Thonk ones, i’d probably just go with thonk. I’ve never really understood why electric druid sells some ICs for double what they should cost… ---

the AS 3340 is a great chip and works fine as a CEM 3340 replacement and cheaper , thanks Dud for the link for that soul of synth builder
