On another subject if anyone has a clear schematic to copy from a manual the one I received with mine is too blurry to make out well. I think I do need to tear into the box and recap etc and having things on paper that I can read would make me feel better. I didn't get a cord with mine and I...

Strike that. I didn't try melting the gel in anything but the microwave but evidently only a high heat will do. There is nothing in that gel that will melt from microwaves and the dish it was in got very hot without doing anything to the gel. The headphone pads will not come apart so you can't...

A good source for a gel would be the wrist pads you can buy for key boards. Easy to cut up but very tacky, a bit of flour or talcum takes care of that and it won't run or leak. I've used them for isolation purposes and all you need are scissors to cut them up. The insides are like sticky jello...

I just bought but have not received a pair of the ESP-9s for total of $150. There is the owners manual with them and according to the seller the energizer is only supposed to be plugged in for testing of low level inputs from the amp. Seemed kind of stupid to me since others seem to need this...

I'll take a look at Frank Cooter, Thank You Unk EriK. bcg27 if my inquiry seemed disjointed I am sorry. You kind of got the idea that I wanted to use old globe triodes from the 30s as the power tubed, not the drivers for building high quality amps for headphones and to use as a preamp too, if...

I listen to 300Bs on my speakers, have a few different sources for headphones incuding a CD player with a volume pot on it, the old Koss cans make it clip, and have been thinking of the possibility of building a nice low wattage SET amp for some better headphones than I use now. There are a lot...

There is a Polk group where you can get some real advice, and if you gave some I gave up after about post 6 because there wasn't much going on besides leg pulling. If you want to go vintage I have liked the phone setups in the Fisher Receivers and 7591 integrated amps. That is a start. You can...

I've been out of DIY for a while and what would you call oxygen free continious cast copper wire if it is only a single strand of magnet wire? What about continiuosly extruded like the Western Electric stuff with the paper cover called Celonese from days gone past when they twisted a pair of...
