Great report, where did you get the real deal J201’s from? I noticed PedalPCB has the small boards to use SMD components but are out of stock. I was listening to the Lemonade Drive and wondered if having the bias off a bit was part of the pedals charm? What did you find. Regards Mark

This is what I was seeing when testing the 2N5457. It doesn’t seem terribly meaningful though. Any thoughts? Regards Mark

Music6000 could you provide a link to this part so I don’t order the wrong part? I hate ordering from Mouser as the postage is expensive. Thanks again to those offering assistance. Regards Mark

But what is your take on the FET in my Lemonade board? PPA isn’t the issue. Regards Mark

I would like to point out that I have used Pedal Parts Australia before and I have found them to be very good to purchase from. I think Music6000 was referring to pop up eBay sellers. The issue here is FET’s. It seems quite a few people have had issues with FETs judging by the links in this...

Thanks I’ll remember that. Regards Mark

I bought the 2N5457 from Pedal Parts Australia. I don’t know where these guys got them from. So are you saying they are duds? Who is a recommended seller? I haven’t read the whole thing yet as it’s a bit long winded. Regards Mark

This is the board, it still has to be cleaned etc. Regards Mark

Well, 7.6K is very close to the stock 6.8K, so that makes sense. I disconnected one side of the pot and the drain resistor is 20K which is quite a bit higher. Here is photo of the 2N5457 in the board. Thanks for your assistance. Regards Mark

Thanks for your link. I did read your article, though if you have greater A/C current flow though the collector resistor, won’t you get a greater voltage drop across the resistor and thus greater amplitude of the signal? Regards Mark

Okay, I removed the resistor and used the 10K pot. It wasn’t even close to being half the rail. I end up using a 100K trim pot and at about 19K (will have to double check) I had half the rail on the drain. I played through the pedal and it was much the same sounding as far as I can remember...

Good call M6000, the VDD is 8.35VDC on the battery that I’m using and the voltage on the drain is 6.97VDC. I do have a 10K pot. I can remove the 6.8K and sub the pot in to determine the correct resistor value. I assume the idea is to have half the rail voltage on the Drain. I will give that a...

What about replacing the BC108 with a Darlington pair transistor or use two BC108’s to make a Darlington pair. This would yield higher current gain. Regards Mark

Basically, I’m looking at great width from the bass control “Filter”, including using a linear 100K pot, as well as having done adjustment over the treble response. https://forum.pedalpcb.com/threads/lemonade-drive-report.7526/ Regards Mark

I have my board at the stage where all the parts are in and I can listen to it. It nails the sound Page gets. However, I found myself thinking it didn’t have enough bass so I replaced the 2.2uF bypass caps with 4.7uF caps as recommended here. Thanks for the tip by the way. I wasn’t fond of the...
