Bigbottle MM/MC Hybrid Valve Phonostage PCB

[ferret]

Hi Gents, got my R-core from here for roughly $40 delivered

R26-90 0-115V 0-115V 40W R Core Transformer 0-165V(0.1A) 0-9V X2(1A) for preamp | eBay

Yup that's the going rate it seems for the R26-90. I ordered one from...
HiFi Audio parts Sotre>>Amplifier kit > Tube Preamp > DAC kit >>shipping to worldwide


Same trafo as the one on eBay... a few bucks cheaper. Diyclub.biz has them for even less - $21, but it looks like you can't create a new account. I emailed them a while back, but never got a response. Chinese New Year?


Can't wait for the board / build.

Interested when you have a GB. Always in for a new phono preamp to listen to.

Indeed the New Year, but now done and dusted. I would have ordered from them but the shipping cost to get it to SA was more than the Ebay one. I do want to get some 200VA R-core trafos from them too, so may order the R26-90 from at the same time - money the availability thereof being the major factor.

P.S. Thanks for the link to DIYERZONE - will check what their shipping costs are.

5 of the new PCBs have landed

I really need to get one built so it can be tested.

Anyone fancy a free PCB on the proviso its built without haste? Just need to know it works really, everything has simulated already so in theory it's all good.

Drop me a PM

They look really smart! Nice one, I'd say yes to your offer but I have too much going on atm so wouldn't be able to build quickly. Sure somebody will be along though.

No, that's ok mate. You haven't heard the one you've just built yet lol

They do look tidy, I agree.

Boards do look great.

I can make one too, but as smangus said, can't do it quicky ...

Ah, that's a shame.

I'll see if anyone else volunteers

I can build one. Just finished a Pete Millett tube amp.

Do you have the means to troubleshoot if required?

 

[comicrcc]

Yes. Have a Tektronix scope audio generator and HP distortion analyzer.

Sweet

PM me an address to send it to and I'll get it out asap

This is just what I am in the market for! Keep us updated on when the boards will be ready and how the final product sounds!

 

[Mull3t]

I'd love one, but can't build it just yet. I'll wait until the larger GB gets going.

Will do!

No worries, I have found a test subject so we'll get on with checking the prototype out and as soon as it's ready, I'll start taking names in a GB

Made some progress with the first MK3 PCB

I'll have it finished in a couple of weeks.

This one is just to test for functionality. The boutique bits can be done later View attachment 818868 View attachment 818869 View attachment 818870 View attachment 818871 View attachment 818872 View attachment 818873
