x0x with BA6110 back to BA622A. How?

Post by 0li »

Hi all, new member here

I hope you can help (can't find a thread about): I have a x0x with BA6110 (and those 4 transistors Q1-4) and want to use a BA622A instead of that 6110.
Do I have to pull the four transistors in order to run the 622? Or can I keep them as they are?

Does somebody know something about this?

the build manual says:
If you decide to go with a BA662, do not solder in Q1-4!
so i would suggest you to desolder them and solder sockets

in any case

I wouldn't go through the trouble, the difference does not justify the change.

to complete this thread:
x0xshop berlin said, that Q1-4 can remain on the board when running a BA622. So I did and it works perfect.
For me it was a good thing to go back to BA622. I would do it again, since I hear a remarkable difference.

do you have a before/after recording? or can you describe the difference?

thats interesting - i was under the impression Q1-4 get removed but maybe it just ignores them with the BA622 in place. i am going to do the same swap soon so its good that you say its made a difference as a lot of folk have suggested its a waste of time. maybe it is worthwhile only with certain BA6110s (bad batch/damaged/duff)?

without recordings the statement that it sounds better is worthless.

I'm currently building a x0xb0x and i'd like to put in a switch to switch between BA6110 & BA622. Would i be enough to switch the power between the two ic's? Or sould i switch multiple connections.

Or maybe just switch audio in or out?

No. the two are different, you wont be able to do it with just a switch. The 6110 has additional parts needed that are not used with the 662

I understand that the parts are different. I asked because i read here that you don't need to take out the extra transistors for the BA622 to work.

You can leave the current mirror in if you just want to use the BA662 but you cannot use both the 6110 and 662 at the same time

Not at the same time, but it would be great to be able to switch between the two, would cutting power to either IC be enough to virtually remove them from the cirquit or am i in for some weird side effects? As you can tell i'm not very much into electronic engineering.

Probably weird side effects. Why would you want to do this? If you want a 662, Just get Guest's clone for $12 and be done with it.
