Hi guys,
Please recommend some decent electronic component suppliers.
"One stop shops" that you can purchase quality and original bits, find all (or most) components at decent prices (EU and China).
Currently looking for someone that can ship all components to populate an existing NRG PLL PRO board.
Thank you for sharing your time and expertise

Isn't there someone on ebay that sells most the components etc for the resistors and caps?
I have a box full of Philips 74HCT4059N, I believe these were used in the NRG PRO boards but would need to check as I'm not 100%

You're right. The 74HCT4059 is a presettable divider IC and was used in the Pro III. It is BCD programmed in four decade stages, and is designed to be programmed by BCD-coded rotary switches. It was a slightly more expensive option, but was used to replace three other divider ICs on the earlier boards, and to provide both the option of rotary switch programming and an additional point of difference from the circuit that Hollings stole from its original designer (and then screwed up because he didn't understand the subtleties of the design).
I've used them for years - they're a convenient solution for programmable division ratios, but the chip is physically quite big, so takes up a lot of board space!

NRGUK on eBay probably has everything you need.
Enigma Components and Dutch RF Shop also sell components.

Thanks for confirming Albert!
Well have a box with 100+/- sitting around, so might aswel flog them off as I have no more use for them

I'll buy a few from you, as I've got a couple of PROIII boards here somewhere that need to be built when time permits.

Be sure that they're 74
HCT4059 - the ordinary 4059 won't go above ~3MHz!
