The FV1 datasheet says that capacitor can range from 15 to 27pf depending on the crystal manufacturer

I just went by the silonex datasheet image defo looks like the dots cathode to me, I could be looking at it wrong though

Just use the original TS808 schematic and the shop pcb image where you can see most of the traces those pads with the faint crosshair type thing go to ground You should be able to work out where the vias connect from the original schematic A wee bit extra work but that's what I do awaiting the...

If it worked before you boxed it that tells you it's usually an offboard wiring error to the DC jack, in and out jacks or 3PDT switch or somethings shorting to the bare metal of the enclosure

I usually solder a component in place and have a quick look using a magnifier You want to heat the pad and component leg at the same time for around 4 seconds and apply your solder till you see a nice flow Clean your iron tip frequently as you go Any joints that look flat, dull, ball like...

I think like most I've been aware of your excellent work for some time Having read your 101 posts you definitely make it easier to understand and inspirational I just wish I had more time to get into it

I like a wee bit of spite.... keeps you sharp I've just started messing with tubes so look forward to learning from your goodself

I should have said it may not be the caps but that's the first thing I'd check Could be the LED or R2 with a dry joint perhaps try reflowing the joints on R2 and the caps test it, if it still pops disconnect the LED see if that stops it For polarity you want + to the most positive side...

I personally wouldn't use tantalum in place of ceramic or film capacitors even though you can Tantalums are indeed polarized electrolytic capacitors and you obviously have to get the polarity correct Normally with tants there's a good chance they'll just blow if you get polarity wrong but not...

God that was super quick thanks Dave Why am I surprised? Excellent I'll definitely give it a go Just for info Wilhelm at different noises on insta is happy for anyone to build, mod, dissect or improve the freeverb This is his first real spring tube reverb circuit it does work I've got it on...

You could try this stuff not the healthiest option though I've used similar stuff to get allsorts of gunk removed De.Solv.it® Sticky Stuff® Remover Liquid - 250ml https://amzn.eu/d/dQuNYka

4u7 will do the job Back in the day 5, 25 and 50 values were common, basically what they had around at the time These days as you'll know it's 4.7, 22 and 47 As @temol says with a 20% tolerance you've a good chance of finding one at 5u from a 4u7 if you want to be exact

I think the pcb is one of @mjv913 (Matt's) own pcbs You can check some of the interesting stuff he does on his you tube channel here https://youtube.com/user/mattv913

Bought one of these a while back based on you can put signal through anything that conducts https://www.ebay.co.uk/itm/193774631445?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=gVVg5_8mTwG&sssrc=2349624&ssuid=VraIHHfoTvS&var=&widget_ver=artemis&media=COPY Put it in a drawer and forgot about...

This sat in a drawer forgotten about worked apart from tails Couldn't suss which of the 4 switches it was on the schematic to check it Anyway contacted Cees (skidmark) the designer who said the switch labelling on the schematic was confusing and sent me some trace screenshots a coupla jumpers...

Congrats on getting it going You're not hallucinating @Chuck D. Bones I did edit out 3 pics two in the same comment when you came in to help I've been away at my sister's so just back today anyway point taken no more memes especially if it's a long drawn out affair it just adds congestion

Damn how'd I miss that I'm forever telling people to go check Chucks Boneyard..... And I missed it! coulda saved a few pages here reading a few pages over there Anyway my complimentarys to you @Chuck D. Bones or is it differentials

That'll be fine you can use either

Happy accident meteors are way cooler than water drops anyway! I'm gonna try it again but this time drop water on and see it I can do some kind of image or pattern with a brush using the water then side spray it For those of you who haven't seen this technique before here's a vid

Fuzzdog DBA reverberation machine with the feedback mod and momentary switch First try at the water drop painting technique as per I glanced quickly over the instructions watched a wee bit of a vid and went for it Looks nothing like water drops more like a meteor shower but kinda cool has a...
