I have forte 2 wich have the original crossovers + upgraded caps. I was looking for a parts list to get started building my own. didn't know if the crites was worth it or not . I have dayton tweeter caps and clarity MR on the midrange.

Hi I have a pair of w5 one with large transformer and one with the small. I have already replaced the small trani. The new kt66 are the gold lion re. these amps are triod strapped. They were rebuilt ten years ago I just recapped again to make sure and used 600 volt. The main someone put in...

1000a results After changing caps and tubes the magic combo that I liked best with my speaker is.. Auricap by Audiance .33 coupling caps The oil caps were to big and the bass was tubby ,solens were bright Orange drops were dull and flat. Other caps simply woln't fit. 12ax7's best of what...

12ax7 I have some rca's GE's and I orderd new EH's JJ's and sovtecs. I will install the k40y coupling caps when they arive and then roll tubes. I will post sound results. I can always use the leftovers for jukebox amps or future who knows. Shawn

Ok its up and running again. I changed those input caps on the 12ax7 to .02 orange drops (not sure but i think those caps kinda suck) both channels came up. And that CRS 02 dose have 7 wires on it I pulled it out of its little hole and counted it four times. I have seen ones on e bay with 5...

Thank you I will test. pin one is .003 and I think acording to scematic should be .002 I will test I did switch all tubes around and problem stayed on the right channel

ok It is pin 1 of 12ax7 voltage on good channel 130 voltage on bad channel 125 Seems I have signal from that pin on both tubes both channels . that oil cap that caused the problem might of been bad it registers higher value. It is hooked to a 7 wire crs 02 whatever that is. No smoke no pop or...

ops yes 1000A

I made a big mistake in trying to change the coupling cap hooked to the 12ax7 I thought it was a .33 and it was a .003 . Now I have no right channel. I hooked the right ones back up. It seems I have signal from that 12ax7 forward. I didn't smell any burning smell or anything. Could that have...

Thanks for all the advise . Been playing this thing out in my shop and man it is a monster sounding unit. Don't remember it sounding that good when I was a kid. But my dad didn't have 98db infinity's. He had old junk fishers. I have the EH's comming in the mail some jan sylvainia driver tubes...

Hey larry where do you get the .33 K-42Y-9 ?

THANKS FOR THE HELP I ORIGINALY MADE A MATH EROR. I get the math of it now. I got it and it sounds good not as clear as it could My altecs have a 1 ohm resistor i use to bias. I will finish the board with the 12au7 on it. what is that little pcb board on the side of transformer that is...

OK maybe I'm testing this wrong? I checked the negitive volts with full wall current. It's about -22.5 on both tubes on one channel The mv across 10 ohm resistor on pin 5 reads 100mv per tube is that 10ma? I found this post: The idle current is the important thing - not the bias...

I have a 1000a that im almost done recaping. I put in solens and the 10ohm resistors. I thought it should be around 25 or 30 mv across that resistor? Shawn

haven't tested to many diods or anything. I guess I need to sit down and voltage test starting at the front end. As far as diods I havent had much expierience. I have more with tube rectifieres.
