Hi Ken,

Welcome to diyaudio.com! Seems like you followed my recommendations to join this vendor bazaar forum. Wish you all the best in your business.

You've got a PM. Please send me the quotation for your Precision Series OPT. I liked the PX3.5SE MK2 you built for me last time but now I'd like try your flagship OPT to compare with the Lundahls I've got. The Lundahl is still the best among what I have IMHO. PX3.5SE MK2 is good but the bass is not as deep as the Lundahl (can't complain though with 1/2 the price the Lundahl costs me!)

Hi Ken

Recently found you in the net and need to know if you can provide R-Core transformers with same or better quality than SHILCHAR models.

I need two 120VAC primaries, two 18VAC secondaries and 120VA power capabilities.

I tried some chinese models and found that they can not keep regulation under load.
I mean that these chinese models are able to produce 25VDC form 18VAC after rectification but when a load is applied the output goes down to 18VDC.... not good voltage regulation.

Can you build a r-core with good voltage regulation ?

Best

Ricardo
