That sounds reasonable... also preferrably quick blow.... GFIs for personal protection around here are usually 20 mA...

That would have to be a very small value fuse in order to have any meaningful protection....

THe choice of speaker element in combination with cab size and design, is vastly more important than the choice of wood....

640F/340C is certainly on the low side.. most pro irons go to 850-900F, but are adjustable.... That Ryobi thing is probably adjustable, but reasonable exact temp's seems difficult... FOr soldering elctronics, too low wattage and temp is not good, as it leads to long heating times, which transfers mo...

In RF circuits, ferrous coil cores will increase inductance, while aluminium or brass will lower the unductance somewhat... I've used this effect sometimes in radio circuits.. No real idea what it will do in a PUP......

I think Hakko is OK, as far as I know. I've been using various Wellers for over 40 yrs, and have at least 4 versions, so personally I stick with those. Weller also has some controlled stations which are more directed towards the hobby market, and should probably cost around 100-150 USD, as opposed t...

I use 350-370C for most things.. slightly lower setting for ICs and small transistors, and small components... for larger parts, connectors etc 370-400. A 40W iron is kind of smallish for larger stuff. When you have temp control, buy the larger iron you feel you can afford. I use 80W Wellers, both a...

Double sided carpet tape....

Well, - you guys in particular should know that a crapton is 2000 lbs, whereas a shitton - or shytetonne for those who prefer - is 2240 lbs or 1000kg....

Piezos in general want high impedance loads, and most piezo mic's solve this problem by using a FET transistor as an impedance converter. This might be one solution to the load problem. Another way is to use opamps in non-inverting mode, where you will benefit from the JFET or other high-Z input opa...

My son wants a Telecaster, and I've been looking at the StewMac kits, - particularly now as they are all on sale.....
Tuners, mic's and stuff are easy to replace, but what is the quality of these kits, - particularly woods and neck accuracy... ?

Steve - what you really need for using Arduino with the saw, is a linear encoder - a pulse counting ruler thingie that's quite easy to interface...

Of course it depends on the transformers, - and several other parameters, but the numbers I referred to are a sort of average for several HiFi-amps, and to some extent moderately driven guitar amps.... things can always be pushed, but not without a cost..

A pair of EL84s usually gives 15-18W in HiFi-amps, 6V6 typically aorund 30, 6L6 35-50 depending on type, - the old metal jacket appx 30-35... There are several designs out there... I'm currently working on a 2x6L6 that's supposed to deliver aorund a 100, but I'm holding it back a bit and going for a...

The movement is lengthwise.. I have no experience with banjos - is there a way to tell if the "drum skin" is not tight enough , or how does one determine enough tension? ( - I was thinking about just fixing the bridge with a small strip of double sided tape... )

A friend of mine has a 6-str banjo where the saddle seems to be moving, constantly throwing the thing out of tune... is it common at all to glue the saddle to the resonator top, or is there another solution??

Possibly because the lead-free motion that hit us.. I sure can understand the environmental aspect of it, on an industrial scale,but for our small scale use for hand soldering, it causes more problems than it saves.. just my 10c.....

Weller TCP tips only fits TCP irons... TCP irons are controlled by a Curie magnet at the back of the tip, - regular controlled irons have a sensor that sits against the rear end of the tip..
BTW - I was assuming you have an old TCP iron - there are other tips to get with other temperatures..

I think there is ome confusion here.... silver solder for brazing and silver solder for electronics is not the same thing. For electronics the use of silver as additive is mainly based on the newer specs for ROHS and lead free soldering. There is also this strange notion in HiFi circles that silver ...
