Re: Magnetic fields
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......

Re: Soldering iron temperature for guitar, amp and effects circuits
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...

Re: Soldering iron temperature for guitar, amp and effects circuits
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...

Re: Piezo Bass Preamp
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...

Re: Just for the fun of it - DIY tube amp
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..

Re: Just for the fun of it - DIY tube amp
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...

Re: Banjo saddle moving
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...

Banjo saddle moving
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.....

Re: Soldering Iron Recommendations
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..

Re: Where is silver solder used, good ,bad?
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 ...

Re: Need assistance outlining earphone speaker circuit
If you google "Headphone amplifier kit" you will find plenty of kits- some with suitable boxes included or as options, but first you need to set some specifications for your needs. What is you intended use, and what will be your input sources? Headphones come in a variety of impedances, from 8 ohm t...

Re: Can someone walk me through speaker design? I have no idea.
One of the problems in speaker design, is that you can make almost all the wrongs there are, but unless you make a dead electrical short there will always be sound. If it sounds good is another story. MDF is commonly used in most commercial designs from cheap to very expensive, although some audioph...
