FED16BT

Has anyone found a replacement for this that’s available?

I have a soundstream amp here and that’s the only thing that’s bad in it .

Or is there a way to make a doubler diode using regular diodes ?

 

[The Lord Flashheart]

I found this link yesterday whilst angrily googling links to damn Soundstream with...

FED16BT to FEP16BT

 

[caraudioguy2100]

That replacement isn’t available

 

[The Lord Flashheart]

Ah right, apologies.

You can hardwire two MUR820s but there isn't likely enough space to do it where there is good clamping force.

 

[caraudioguy2100]

Would the RURG3060C work for these ?

Or are the 2 different types of diodes

 

[Perry Babin]

That diode is a positive rectifier and much larger. Would you have enough space for that? The APT30D60BHB is a doubler but with the reverse configuration.

 

[caraudioguy2100]

I have enough space to put a larger case style in the amp and still have enough clamping force

 

[Perry Babin]

Are there parallel rectifiers?

 

[caraudioguy2100]

The amp uses 2 rectifiers in it both fed16bt.

They are both missing

 

[Perry Babin]

What model?

 

[caraudioguy2100]

Soundstream D100 ll

 

[Perry Babin]

That explains having enough space.

 

[caraudioguy2100]

You told me to use the MUR820 to make a doubler .

Would the MUR1520 work also or not ?

If they will work how do I connect them in circuit .

 

[Perry Babin]

You can use the 1520. For this amp. a 3 amp rectifier would likely survive. I keep the 820s in stock, that's why they came to mind.

 

[caraudioguy2100]

So I would need 4 of them in place of 2of them correct ?

Also do I connect the 2 legs to pads 1 and 2 then the tab to the center pad or how do I connect these into the amp ?

 

[Perry Babin]

Yes

You don't connect to the tab. Match the internal diodes of the 2-legged rectifiers to the ones in the doublers. Look up the datasheets if the cases have no markings.

 

[caraudioguy2100]

I guess I’m stupid when it comes to this .

Here are the 2 data sheet pics.

I’m not sure How to connect these in circuit .

Any help would greatly be appreciated

 

[Perry Babin]

The 1520 is the same as the 820.

 

[caraudioguy2100]

I ended up going with FMU32U since I had a couple of them here .

Am I over looking it or does this amp have no gain control ?
