I would be interested in seeing pictures of this, if its not too much to ask.

Okay dokes, right now its messy as and can be done a LOT cleaner and safer, but alas to give you an idea I`ll try and take some pics some time.

Had a go at Stan's non polar upgrade to the opamp circuit a few days ago and like the changes to the sound. Still running in but I can detect more depth in the music and the treble has a bit more life without being over done. I used the Rubycon 47uf/16v caps from ebay.

This is with the standard LM4562NA opamps and a 15v linear power supply.

Nice one Stan (and Leo).

I have found these 47uF 16V Black Gates at Parts Connexion whom I've used before. Could someone who has done this please check that the dimensions are ok? I only need four for the line out so price is not an issue.

The mod needs non-polarized caps to be effective. I am not sure those BG are such types.

Anyhow, I might have one spare set left over. If you are not doing the headphone section mod as well let me know. I can post you a set of the caps with the Caiman PSU next week for you if I do have enough left.

Thanks Stan, I'll go with that offer since I'm only doing line out. Can you adjust the PayPal payment before you send it to me?

Hi Martin,

Those BG caps diameters are a bit big. They are 10mm dia and the Rubycon's I used are 8mm dia and only just went in (touching together).

Stick with Stan's as they look to be Rubycons also (same colour and overall look anyway).

Regards

Will do, thanks chrism.

Hi Martin,

Sorry to butt in here, but have you received the new bearing yet for your 1210? Chris has got his :)

Marco.

Hi Marco

Not yet - but then nothing has been delivered to Basingstoke for the last two days. I will let you know the minute I receive it.
