Is anyone considering working on a PCB for the bias sections? I'm thinking I might tackle it since it would be a nice add-on to the diyAudio PCB board. In order to have some adjustment to the output voltage, R1/R11 and R2/R14 would be a potentiometer with D1/D5 connected to the wiper, right? It also looks like Elna RFS 100V caps could be used all around.
4 component ... p2p pbc like this Multipurpose PC Board with 417 Holes : PC Boards | RadioShack.com ..
Do you have Radio Shack stores in Italy? I always thought it was only in the US; unlike McDonald's which is everywherte.
HI Antoinel , no not in Italy , I use the first link I find as I don't remember the the correct name of that type pcb .. LOL 😀
digikey mouser farnell are here
PS after 36hour no info from jensen... if I drop direct the money by paypal account ? I will push my order ?? 🙂

Thanks for this info. If your answer was yes, then I would have loved to see a picture of the RadioShack store front. I believe one needs to pay first, and then the merchant [Jensen] sends /ships the transformers. I use Paypal within the US [to eBay, Audio DIYers etc.] and my wife had on occasion used it to buy stuff from China.
Best regards.
Sure ,but normaly he must accept my order sending back the order form ,I pay , jensen ships...😛
When I called Jensen and left a voice message, they did not call back in more than a week. I had totally forgotten when they called me to take my order. If you insist they will get back to you.
Many DIYers have purchased from Jensen; but I did not. I hope those DIYers who dealt with Jensen can help, and shed light on Jensen's selling protocol.
Best regards
I am in the process of writing the article, and you can expect to see it posted
in a week or so.

Mr. Pass why did you use another Jensen xformer and not the same you used in F6.....?
I suppose you needed flexible wires for easier connecting ...........😀😀
And to be more serious.... I suppose it may have a better bandwidth without feedback.

according to datasheet , they're practically the same , except mounting arrangement
but , I'm also puzzled , waiting for Papa's comment

it is sort of 1:2 , but only if connected as per test circuit 1 in datasheet (primaries in parallel , while secs in series)
I think Pa sez they're 1:1 , if we agree that's ratio from input side to gate ... as connected in amp itself ( just as info that he's also taking them as 1:1)
when connected as regular repeater - 2x (so called ) 150R series as primary : 2x (so called )150R series as secondary , that's typical (so called ) 600:600 xformer

I talked to a nice lady on the phone on Wednesday morning and I found them in the mail this afternoon. Phone orders with CC probably get quicker turnaround than e-mails.
