My new Paul Hynes PSU is coming today.;)

I know I have to remove the transistor,Q1 and the stock transformer.

I also have been advised to remove R2, R4 and C3. What happens if I don't remove these 3 extra components immediately? I've seen several pictures of new PSU's being used without these components being removed?

Also should I just snip them out or desolder them? The only reason I ask is I'd rather not keep removing the PCB and bearing unless I have to?

Thanks

Andrew

I didn't remove the additional components when fitting my LDA PSU.
It seems to work fine. I don't know how different it is though.

If you need to remove the components, personally I would unsolder in case you want to retrofit the original PSU.

Thanks.

Paul definitely recommends removing these but was also trying to find out the difference.

Ask Paul? I would be interested to know the difference.

It's all fitted.

I bypassed the mains switch as recommended and also removed the 3 extra components and Paul told me they were redundant. I desoldered all rather than just cut.

It's sounding very good so far, like a veil has been lifted and finer details common through. I'll wait until it's full run in as the cart is also brand new but I'm sure it's been well worth it.

Good news.
I need to refit my PSU as it went belly up.
Sent it back to Nick at LDA. He received it yesterday. He has already diagnosed the problem, fixed it, and got it ready to send back to me. Excellent customer service.

I may look at de soldering the additional components, but it makes refitting the original PSU more difficult.
I am glad I left them in place, as I have been using my deck with the bop board PSU fitted recently.
