has anyone compared the ones made in china and the states? not saying they are made here.

I blew out my diaphragms on my horns in my Altecs and replaced them with the ones from china. is there much difference in the US models?

Im in Houston not much service out here

he knows I'm using 2A3s.

From Craig at Eddie Current (moth) You need to measure the bias resistor to see what the bias voltage should read. The 45 tubes need about 36mA, so if the resistor is 1 ohm the meter should read 36mV. Make sure you have the correct tubes, I have not seen a 45 tube that looks like that. I don't understand what he's talking about!

why am I only able to load one picture only?

Bingo!

I will get the all tubes checked out Friday. Do you think the Amp is worth saving? if not I still can sent it back to the estate. I paid 1,100 for it. here's the deceased owner thread on the amp http://audiokarma.org/forums/index.php?threads/moth-s45-arrives.1079/

Here's from Craig at Eddie Current:All Moth amps had manuals with schematics. If you got the amp it should have been sent in a wooden crate with the manual. That amp is 17 years old and it is likely the electrolytic caps are dried out which would account for the buzz. I don’t have any documentation on the Moth amps, and don’t work on them.You need to measure the bias resistor to see what the bias voltage should read.

What does grounding a RCA do? Here's a link to all the picture's: http://audiokarma.org/forums/index.php?threads/moth-audio-45.791782/

I can't find a schematic.

It also can take 45B's

the link did not work.

no buzz when the when I pull the rectifier tube outs it have to be a ground

buzz at all volumes with nothing connected. heres the buzz

here's the tubes. that would be great if it is. what brand is this? is it cheap?

theres a buzz at all volumes even changed the power cord

the amp sounds great but it has a hum and the guys on AK sent me over here. I don't know the how or what the bias should be? I can't find and info on them. I tried Craig but no reply.

Does anyone have any info on this Amp? I bought it from the estate of a orignal AK member.

here's the only ID on the speakers in the cabinets.

All cleaned up.

Here's the one in the cabinets. the guy really carved the boxes getting them in.

the newer subs are in the LaScala's and were purchased in 2003. heres the marking on the box. i'm wondering why the guy replaced them. they sound great. now that I look at them they are both K43's the newer one are EP's. One side of box says K 43 E and other says K 43 E.

Well, I picked up a pair of La Scala's today still in the box with extra woofers. i can't figure out the difference between the subs it came with. k-43 88-44 are in the boxes and K-43-EPs are in the cabinets.what are K-43-EPs. bear with me I'm a newbie.

sorry for the newbie question. I am a long time Audiokarma guy retting into Klipsch's. why are the one's made in the 80's going for 1/2 the price of 70's. is it like a fine wine? I was looking at the la scalas with my mcintosh tube amps but I maybe able to get into a pair of 80's Klipschorn's
