Default Bridgeclone question

Im planning on building bridgeclone using my free lm3875,s (thanks national). If I was going to use a zobel network on the output, do I need a zobel on each output to ground or can I use a single zobel between the outputs of both lm3875,s Thanks

I say leave the options open. Start with across the terminals but be prepared for two networks down to ground.

I have a question, where the H...l can we find LM3875 here in sweden??
Elfa doesn't carry and Farnell and RS Components won't sell to non corporate.

And National won't send to sweden I guess we are terrorists or something like that.

Since I am from near gothenburg got anything near us??

Suggestions???

Thanks

You could try Arrow but this is a gamble because they only do business with companies. Why can't you use LM3886 which is easy to get and better in all respects?

National sends to Sweden, look here and here.

Why don't you step in at ELFA in Mölndal and Krokslätts fabriker and just buy LM3886?

I'm probably gonna have to go and check Elfa out.

It's real simple cause my dad works in gothenburg so he can get them real easily for me.

I just wanted the LM3875 to try because of the said midrange caracteristics.

But I guess it won't make much of a difference.

Thanks anyhow.

Any good Hifi meetings coming in gothenburg??

Is this a fact or just a rumour? I have a hunch that LM3875 and LM3886 is more or less the same but with different selections (the 3875 couldn't deliver 68 W) or the LM3886 has a larger chip.

Actually you are probably correct.
It's only hearsay from the guys in the big clone thread.

I'll try the LM3886 instead and i'll go for the inverted mini clone ...and probably make a bridged one for a tiny subwoofer to ....for use in my bedroom perhaps.

I can get real big heat sinks hear from old electrical parts ...
Or perhaps an old cooling fin from an SLOT1 Pentium2 pc

Thanks for the advices.

Anything other that comes to mind??
