Borbely Millenium 200 - Monoblocks PCB Set, all assembled and tested, optional Transformer

Hi. I have too many amplifiers, these ones have to go. They are the complete PCB sets to build the Borbely Millenium 200 Mono-block amplifiers, all assembled and tested with the two main supply big, large power 120000uF caps. You just need to mount them into the proper chassis to have some of the best amplifier ever made...

All PCB are very high quality, designed and made by me, 2oz copper, and much better than the original Borbely standard ones, with hi quality parts (Caddock MK132 & MP9100 and PRP resistors, Black Gate, MultiCap, Silmic and Cerafine capacitors, etc, only the best). Check the pictures, I includes some pictures of my test prototype where I tested the amp pcb.

If you are interested I can also sell you the pair of very high quality, custom made, potted 1KVA Plitron power transformers. They are dual 115V primaries, and support 115-120 or 220-230V international AC supplies. The internal power supply used for the Front end and protection can also be selected from 115 or 230V, so these amps can be used in Europe or in other foreign countries without problem.

The amp has soft start and output protection circuit, ground lift circuit (can be bypass by switch), AC input DC filter, Output Mute timer, discrete HexFRED 600V, 25A rectifiers, high capacity supply filter United Chemicon 120000uF, 63V, KMH Series caps. The front end, fully discrete used the famous J74/K170 matched JFET input and the J313/K2013 driver MOSFET and also for the discrete regulators (yes, Borbely was in advance to Pass at the time 😉), and the final is using matched set of 2SK1058/2SJ162. The main amp front end pcb has also the latest discrete regulator Cascode bias mods done.

I made an extra set of PCB with two AMGIS potted toroid to supply the front end independently of the final.The final PCB was designed in two half PCB, so you can mount each polarity on its own heatsink, doubling the original design heatsink surface, so you can crank the bias even more. One of my friend did that with great result. It is up to you, one single or dual heatsink...

The amp has balanced and SE input.

Just in parts they costed me 1500$CAN per monoblock with the custom Plitron transformers... Total of 3000$CAN

So I'm asking a fair price of 1000U$ for the complete parts kit, excluding the custom Plitron transformers, plus shipping and 3.5% Paypal fee (or use friend and family).

Today the amps would cost at least 4k$-5K$ to build, if you can find the parts...

If you want the pair of 1KVA Plitron transformer, let me know, keep in mind they are large and heavy, shipping will be expensive!, I can discuss the total price accordingly.

The kit will come with extensive documentation, original Borbely docs, all PCB schematics and pcb silkscreen, detailed BOM and I'll help you if you have any question. This is not a beginner project, but an expert one. All PCB are tested and certified to work, but it is a high power, high current and rather high voltage amplifier. You need to know what you're doing working around this beast...

This kit was designed to be my reference amplifier, no expenses was spared to build it, but sadly I'm not in a different place and the kit has to go.

I'm open to fair offers, but sorry I won't give away the kit for free 😉 Hope you understand.

Excellent, it is three of my audiophile friends amps. Fast, accurate, transparent, good bass control, the higher the bias setting, the better. Being monoblocks they have excellent channel separation and imaging.

Did I mentioned the kit includes a protection circuit, startup mute, output dc, overheat? With various display leds.
