Nice going Moe

"works for now" is good....

just leave them as is? i was thinking about it but everyone seems to solder them on. wasnt sure if that was a no-no or not

 

[laatsch55]

There will be resistance building up eventually on those spade connections. Soldering is recommended. I've worked on a lot of amps that leave those spade connections on, but you a solderin MO fo, so ya outta solder em. ...

anyone have any faceplate bolts laying around they want to sell me? i forgot i needed some and the ones at the hardware store have markings in the heads. i may go with allen or phillips head if i cant get the factory bolts...

I had put a set of these draw handles I got off ebay they looked pretty good for $12 now I have a set of Perry's handles on it. but if you go the hardware route allen would look better to me than phillips

This is it with Perry's handles

Yeah, the drawer pulls will work but the original style look better. I have used both. Glad you got them to fit on the 400

 

[moewillis]

i dont think i want to put handles on. i really like the factory bolt setup.

 

[laatsch55]

Black oxide Allen heads look pretty sharp with a silver faceplate.

Well I had to put something on there while I waited for the good stuff lol

so i got this unit finished up on wednesday evening. put it on a dbt, relay made and everything worked well. pulled it off dbt, set bias and checked offset and voltages. i left it on the bench until last night when i brought it in and hooked it up. it immediately blew the 5 amp line fuse. so i pulled it back out and into the garage where i pulled it apart and double checked for wiring issue or to see if something had rubbed. everything looked good. i put it back on the dbt with an new fuse and it fired right up. everything still checks out fine....

is there a chance that the in rush from the larger caps charging took out my fuse? would it be inappropriate to try an 8 amp fuse? any other ideas?

thanks guys

 

[laatsch55]

A rail fuse??

 

[moewillis]

the incoming line fuse (dont know what to call it).

not the rail fuses. it had 2 shorter 8 amp fuses for the rails and a single (what i would call more standard) 5 amp fuse

 

[laatsch55]

10 amp slo-blo for the mains in and 5 amp fast blo's for the other 2.

 

[laatsch55]

Congratulations on the build BTW...looking good!!

thank you! i'll snap some pics this evening. should be a pretty familiar site for most people here

 

[laatsch55]

Yeah, but we never tire of seeing those pretty green boards put in successfully by folks!!

Ha, I did the same thing with my build, AGC was fine in the workshop, once amp was moved to the main system it would blow the fuse on power up. Lee gave me the same advice, a Slow Blow fixed things.

 

[roccus]

Congrates Moe your gonna love you new amp

 

[moewillis]

those leds are bright! any way to knock them down a little?

i'm going to move it down to my bottom shelf where my tape deck sits. these were all last night putting it back together and getting it in. no blown fuse this time. i got to quietly listen for a while and it does low volume surprisingly well. i'll get a chance to stretch her legs a little more this evening.

Yes, change the 150 ohm times 8 ballast resistors to something higher in value like 200 ohms, 240 ohms, 270 ohms...

It is your amp, set it up the way you like.
