That's one of the risks of modding these players, before you know it the rest of your kit is the bottleneck

What is that tube amp?

A decent set of headphones and amp are very hard to beat for detail

Be very careful, it can end up an expensive hobby

Nice one Phil.

I use a Marantz Pm-66KI and it's fitted with Black Gate caps, silver mica caps on signal line, Schottky bridge , silver wire on signal input to amp pcb , good rca cons and damping. These mods have really improved the amp.

I use Mission 752F with upgraded caps in xover and rewired internal wire with the same wire as speaker wire.

I actually have 3 marantz PM66 KI amps for my 5.1 system with mission 75c center and 751F rears

Yes, I'm pleased with the headphone setup.
I wonder occasionally about upgrading them, however, I still hear more and more with each CD mod, so I haven't outgrown them yet.

The grados I got cheap off of Ebay (about £60) and the amp and its PSU I built out of spare parts, and maybe £20 in extra bits. So cheap so far.

Having heard the headphones, I now know I want to replace the speakers and amp. It will be a mainly DIY affair, taking probably many years. Fed by the Marantz.

Anyway, I'm going off subject. Sorry.

Now need to find a new method of mounting my Kwak clock so there's enough clearance below for bigger caps and order some parts.

I mounted my Audiocom clock on its side using short solid core wire and a little hot glue.

Here is an old pic

Nice amps Brent!

Ok, can't stay behind now , here's some details about my setup....

Amp: DIY Ultralinear KT88 class-A push-pull tubeamp, solid silver & teflon signal wiring, Elma & Holco stepped attenuator, Auricap coupling caps, Kiwame anode resistors, BlackGate kathode caps.

Speakers: DIY Vifa Vivace '94, silvered & teflon internal wiring, MKP & KP-SN caps, modified tweeter, bitumen and Pritex damping.

Need to have a bit of a think about mounting.
Your clock is tiny! Mine was the first Kwak clock I made, and I used some very nice, but big polyester (I think) 1uF caps in it. There about an inch high, as well as some electrolytics.
Currently, its just mounted above the decoder using a pillar screwed to that hole in the corner.
All was fine until some of the caps grew up

For a while, I also had a small board with three 7805s and associate caps floating just outside the case by a collection of wires. Worked brilliantly, but needed mounting quick.

Will probably fit another board with regulators on somewhere as well.

Nothing is finished yet, so there is scope to do all this.

Nice work Ray

Phil I just drilled the side of the internal cabinet and used stand offs for mounting the reg pcbs. There is enough clearance from the screw heads to the lid too.

very nice work

diy is very contagous, preamp amps cdp speakers.

ps how long does it take to toast your crumpets

brent
i like the layout around the sides.
shall take inspiration from that

allan

just been informed my tent clock has arrived
now need to build reg psu for it,

[philpoole]

Yep, that's the sort of thing I've done. Hopefully, will be doing a bit more of that with time

I also have decent phonos hardwired to the opamp outputs, but they have to be attached to the rear panel which is inelegant as they're soldered and chassis mounted. Fine if you don't want to dismantle things.
This is probably why I will delay the coax mod 'til later. more delicate parts.

At least its all screw terminals so it can be removed easily if needs bed (except the phonos, terminals would defeat the object).

Maybe the whole player needs re-enclosing?
Perhaps that way, there could be rather major mechanical improvements

agree with you totally

thought about extending connection so i could keep the pcb external while doing mods

coax connections are last

must be a major adventure for brent to remove pcb to mod
