I called those guys and I have to say, not much help. I told them what I had and what I wanted and they said "Bring it in. We'll do that." Wouldn't give me a price range on it at all without bringing it to them which is not a close drive for me. Didn't really rub me the right way. I'm sure they are great at what they do but a bad first impression means a lot to me. Anywhere else? Maybe someone more personable?

Most places wont give you an estimate on something like that because they have to test it and see what needs servicing first. Some may give you a ballpark figure, but things could change very quick once they peek under the hood.
 
Looking for a decent portable headphone amp. Something for an mp3 player AND my laptop. I use Sennheiser HD280 pros. Somebody recommended the Fiio E5, but I have a budget of about $50. Not opposed to used.

Awesome. I will keep that in mind. Some cool kits on there.

If you get one, let me know, I have some nice OPamps laying around to put in your output stage. Matter of fact, Im pretty sure I have a Browndog dual to single OPamp adapter so you can run a pair of nice beefy single OPamps. Youll get way better channel separation and eliminate any sort of crosstalk you may get :). Im not using em, so if you want, PM me your address when the time comes, and theyre yours, gratis.
 
I am not too sure what any of that means, but if you tell me where to plug the stuff in I will definitely take you up on that. Thanks!
 
The OPamp is the small socketed chip on the CMOY PCB. Thats what actually amplifies the sound of the amp. You can swap em to get the sound signature you like.

Any interest in helping to get my blaupunkt Arkansas stereo up and running? Lol inherited this from my grandpa when he passed away last year, they brought this back from Germany after WW2 when they moved back to the states. Turntable spins, radio lights up, but no sound.

Any chance you could take a picture of the insides? What does it do when you power it on? Im wondering if its a late 1950s/early 1960s model, as stereo sound wasnt introduced to the consumer until 1957 or so. All consoles prior to that were mono.
 
Bob - I'm thinking of bringing one of my turntables up from the basement to hook up to my surround sound receiver. Any reasonably priced phone phono pre-amps you'd recommend?
 
Hey tin...


I just bought a pair of speakers that are 4 ohm 125 watts.... Can I power them with my reciever thats 8 ohm?
 
Which amp is in question? A speakers impedance rating isnt a constant value, impedance fluctuates all across the frequency range. Usually, the lower frequencies, under 100Hz or so will most often dip lower than 4 ohms...even down to 1 ohm in some cases. The impedance is highest in the higher frequency range, usually hitting upwards of 30 ohms. If the amp isnt beefy and lacks the current to drive lower impedance loads, youll want to be careful.
 
Right now I've got them hooked to that adcom amp just test drivng them. I plan on running them off my yamaha reciever as rear speakers in my home theater set up. The speakers in question are Ohm walsh 2's, I think I stole um!
 
Yeah Ohm Walsh 2s need some beef, and Yamaha sure dont make it :lol:. Leave em on the Adcom to be safe. Adcom is known for being able to drive very difficult loads. Those Walsh 2s will be no sweat for it.

I can almost go max vol befor the reciver shuts off, lol. These things sound pretty darn good, Im impressed.
 
This is why tubes cost so much. Awesome craftsmanship. Theyre not something thats mass produced, most are made by hand.
