Dear Antonio, Dear Nikos, and all others,
Thanks for your feedback, sorry for not answering faster but I have been quite busy recently... I am please to see that everybody received the PCB and like it, I am sure you will also like the sound, I am still trying to understand how to use a sound card to make some audio measurement, but as I say I don't have enough time now 😡
I have received several demand for more PCB's, even one person ask me if I could make a group buy but I have never done that and I don't know how to do that ? However, I could perhaps ask the PCB shop (EuroCircuits) to make more boards if there is enough interest. You will have an idea how the PCB look in the attached manufacturer file. If you are interested just send me a PM and I will see how many pieces could be built, for information the cost of the PCB for the previous batch of 10 pieces was 20 € per channel, 40 € for a stereo amplifier. Don't worry if you didn't get a quick feedback, I am not always on line, I do that for fun and I am please to help others as I have been supported in my project, but it take a lot of time 🙂
Best regards,
Marc

Let's start to consolidate orders....count me in. Thanks !
silvercosworth : 6 pcs (or 3 x stereo )

Hi everybody,
It seem that we will have enough interest to produce a new batch of PCB, about 7 stereo set have been requested 🙂
I received some PM requiring a BOM for the amplifier, therefor I add one in this message (it is a mix of English and French, but should be understandable anyway...).
I had some people asking for the price (even if it was indicated in my previous message !) and I confirm that it is 20€ each channel, 40€ for a stereo amplifier (about 24 & 48 US$, but I need payment in Euro because I have no US$ account...), plus the shipment cost depending of your country. Please give me by PM your email and address to get the exact cost including shipment.
I have received also some request for the EL84 version, however this one is no more available, but the EL34 version can use 6V6 tubes instead of EL84 with the same result (see photo) or may be there could be possible to use an EL34 to EL84 socket adapter ?
I will wait one or two weeks more to give the time to everyone to confirm and to pay, and after I will order the PCB's...
Have a nice week-end,
Marc

Hi Marc
People might be asking prices since the price of pcb's vary with the quantity you order.
As an exemple a pcb like the one of this GB is 100mm x 127mm and cost 34 Euro for 10 of them + shipping. If you order more the overall price should normally diminish.

Eric

I am not sure which circuit (or which version of the Baby Huey) you implemented. Can you post the schematic?
Hi Eric,
You are right, the price of 20€ per board is based on a qty of 10 pieces.
The PCB are made by EuroCircuits Eurocircuits – Online PCB Prototype and small series specialist and you can see the price on their site. As an exemple, for 20 pieces it will be about 14€ and even 11€ for 30 pieces. The boards for small quantities are manufactured in 7 working days, but price can be even lower for higher volume : if manufactured in 20 days for 40 pieces it can go down to 8€ !!!
Until now we have demand confirmed for only 14 boards :
silvercosworth 6
rongon 2
scd 2
leejh 4

Marc

Prices from EuroCircuits are roughly 6 (six) times more expensive vs other pcb house like PCBway and others...any reason why you are using them ? Just curious.

Hi Marc,
Thanks for starting a GB for these boards.
Can you give me an idea what the parts cost will be, including transformers, excluding enclosure?
Thanks,
Laurens

Hi Eric,
Regarding EuroCircuits manufacturer, I work with them since many years and they have always a very good quality on each batch, they produce in 7 working days and they are checking all design before manufacturing which can save a lot of money in case of routing mistake.
I know that Chinese supplier are very cheap but the quality is not consistant and it may take one month to get the boards...
Last point, European suppliers include taxes which is not the case of Chinese suppliers and goods may be confiscated by custom (this happen to me once for a R core transformer!).
Hi Laurens,
I have no exact idea of the total cost but you can use the BOM since most part came from Mouser. The most expensive parts are the output transformer and the tubes. For the Hammond output transformer you can find the price on Mouser too, the Toroidy transformer are very competitive at 55€ each ( TTG-EL34PP TOROIDY - Transformateur: de haut-parleur | TME - Composants electroniques ), but I have not used them until now, one of the amplifier PCB user buy them and is happy with them (the are very heavy also).
For the tubes you may spend between 50€ (JJ) and more than 200€ (TAD) for quad matched EL34 ) Search results :: Banzai Music GmbH ) and 25€ to 50€ for two 12AX7 ( Search results :: Banzai Music GmbH ).
For your convenience I add again the BOM translated in English 🙂
Now we have demand confirmed for 24 boards, the price will be down to 14€ !

Hello,
I didn't expect so many demand, we have reached the quantity of 30 boards which mean 15 stereo amplifier, the good news is that the price will be of 11€ per board now 🙂
I don't think that the price will change significantely now and I need some missing mail and post address to send the payment informations...
silvercosworth 6 pls PM email & post address
rongon 2 OK
scd 2 OK
leejh 6 OK
manniraj 2 pls PM email & post address
carrier bag man 2 OK
matejsirk 6 pls PM email & post address
rene 6 OK

Hi Marc,
I had PM you my details days ago, maybe its still under moderation...as everytime i posted something, it says moderators need to verify my account.
Is it ok to post my shipping address here if you still can't find my PM ?
Thanks.
