Crown Straight Line One, any good ?

[SirPaulGerman]

I have a none working Crown Straight Line One preamp, the Crown is not working, I have no clue how it sounds, does not have phono section, I dont need one.
Should I fix it ? is the Crown any good ?
I was going to pair it with a Phase Linear 300 amp.

[SirPaulGerman]

Here are the spec, are those better or the same as the Phase linear 3000 preamp ?
Op amps are 5534
what are the grey with a red band, capacitors ?
are the pots good quality ?

Should be a nice preamp. I have one but use it only to power some phono amps from Crown.

It is not loved like the SL-2, the 1 rack unit fully loaded preamp but the SL-1 should be great without the tone controls and other things the SL-2 offers. A minimalist approach.

Mine was cheap and ugly, missing letters on the faceplate. I might get the faceplate engraved one of these years.

What is yours doing/not doing? Check the power supply, reseat the chips...who knows maybe it will work.

 

[SirPaulGerman]

I am not going to touched, my tech is going to do it

according to the manual it has 10 .1MF 200V Filmatic, cant find any wima parts for those film caps, any other film capacitors to use ?

 

[8991XJ]

Yes, those 10 filmatic caps. They are just fine. They are not electrolytic that grow old and don’t work right.

but if you must, any very good film cap should be fine. Lots of brands out there.

Panasonic and Kemet to name two.

Mundorf if your 401(k) can tolerate it.

The date codes on the electrolytics are late 70's. The chips appear to be early 80's. Sounds about right as the PCB is single sided without plated holes. Most everybody went to double sided boards by early 80's. Plated holes reduces cracked solder joints.

 

[SirPaulGerman]

I was thinking about the Cornell Dubilier 940C or 930C for film caps

Aragon was still using shitty boards well into the 80’s.

Film caps for 100uf are very expensive, where do I get good quality and good price for 100uf film capacitors ?

 

[mr_rye89]

I'd just go with audio grade electrolytics there, a 100uf film cap won't fit
