Having a big clearout of all the stuff I was saving for a rainy day but have no immediate use for. I'm almost giving this stuff away at these prices so please, no offers.

All prices exclude postage of your choice.

The larger heavy items I will only post in the UK (heatsinks & traffo)

IMPORTANT:

Please reply here as you'll get a quicker response than emailing me.

Payment is via cheque, cash on collection.

---------------------------------------

13 pairs of Hitachi/Renesas SK1058/SJ162

Click the image to open in full size.

Thats 13 x SK1058 and 13 x SJ162.

Packed in an anti-static IC tube for protection. Great L-Fets these, wonderful sound with a good circuit design such as Rod Elliots P101 or Randy Slones Totem. All from same batch so should be good matches.

Around 130 worth here.

50

---------------------------------------

Krell KSA50 mkII PCB's

Click the image to open in full size.

These are the same boards as per the groupbuy in the 'Krell KSA50 PCB' thread over in the Solid State.

Designed by Pinkmouse (Al) and manufacturer by Advance over in the US. Stunning quality with double sided, solder mask, silk screen and scoring for easy seperation of driver and output boards.

Each board will do a single channel of amplification and since there are 6 boards here that a potential of 6 channels.

I'm looking to recover only my expenses for these boards and I am NOT making any profit on these. I have little time these days and I'm already comfortable with my ESP P101 amps that I was going to replace with the Krells.

Here's a couple of shots of Still4Given's boards with components mounted (Scroll down to bottom of page):

http://www.diyaudio.com/forums/show...5846#post725846

By all accounts from folks who have already built the boards, reports are very good on the sound quality - hardly surprising since this is a Krell!

Bill of Materials(BOM) will supplied with the boards and the boards are silkscreen with component locations relating to the details within the BOM. Also there is a wealth of advice over in the thread linked to above, so I'm sure someone would help out if you get stuck.

Price per PCB(1 channel) is 15

---------------------------------------

2 x ESP P39 Softstart PCB's

Click the image to open in full size.

Will include the password required to access the constructors area of the ESP site for detailed assembly instructions. Along with a printed hardcopy for reference.

Basic details here:

5 for the pair

---------------------------------------

ESP P101 amps (200w per channel 8ohm)

Rod cites this amp as a reference design here in his project overview:

http://www.sound.westhost.com/project101.htm

All fully constructed and working Rod Elliot P101's (High Power Version 200w into 8ohm) featuring 2 pairs of Hitachi SK1058/SJ162.

Very neat and tidy builds on each, soldering is all clean and solid. All fully tested and confimed fault free. Been used for around 300hrs at least since I built them in April. These are very nice amps for what is pocket money. Would be perfect for turning your passive speakers into some decent active ones.

2 x Boards using standard components ie. 1% metal film resistors, 10% polystyrene caps and Elna electrolytics.

20 EACH

4 x Boards featuring higher quality components ie. matched 1% vishay metal film resistors, matched 5% WIMA polyproplyne caps, Black Gate Electrolytics and two matched pair of L-FETs These are really nice sounding amps.

20 EACH

---------------------------------------

0.5cw Black Anodised Aluminium Heatsinks

Click the image to open in full size.

6 of in total and excellent condition, cost me 18 each back in March from Farnell UK.

Size is: 12.5cm W x 15cm H x 5cm D

5 each

---------------------------------------

40v, 12.5A, 1000VA Torroidal transformer.

Click the image to open in full size.

230v primary, 40v dual secondaries (40v-0v-40v), 12.5A Current rating (1000VA).

-Diameter = 167mm, Height = 70.5mm

-Regulation:4%

-Weight:7.5kg

Manufacturer data sheet here:

http://www.farnell.com/datasheets/57433.pdf

Bought in April for 56 from Farnell UK, perfect condition and never mounted. All wires are clean from solder since I used block connectors. No buzz, hum or other stange noises, totally silent.

Includes in-rush current limiter and comes with mounting plate, bolt and original box.

Hi,
I'd be delighted to take the four high-spec ESP amps and four of the heatsinks. I'll have the toroid too if it'll run the amps (or at least one pair of them) up to somewhere near their full output. Cheers!
All the best,
John.

On reflection I'll have the soft-start boards too if that's OK- bound to be useful!

Hi John,

The 4 high spec ESP's along with 4 heatsinks are yours - the heatsinks will be ideal because they are already drilled to mate perfectly with the P101's.

The Toroid was also used in conjunction with these and again is perfect. I powered 3 x boards from this single toroid via a large bank of PSU caps.

All the kit was used to tri-amp a pair of active speakers.

Email me at:

zeroex_15@hotmail.co.uk

And we can talk some more.

Yes I have a complete Bill of materials for P101's along with detailed construction steps.

You don't get them though unless you buy a board since that's Rods intellectual property.

Hi again Shin, just tried to email you and got an 'undeliverable' bounce back. Is there an underscore or something being obscured or missed out, or do I need to close up the gap between 'zeroex' and '15'? As to adding to the order- just phoned a friend who's building some NaO bass bins, and he's keen on the remaining ESP boards and heatsinks. So, nearly a clean sweep!

The email address is:

zeroex _ 15 @ hotmail.com(remove spaces)

For some reason I added .co.uk where the .com should be. Should work now anyway.
