Got a load of bits and pieces for my technics sl150 power supply board delivered today, shall spend some time tomorrow pulling caps out and replacing them, pulling switches apart and sorting them too. It has a tabriz arm on it, cart is an at440mlb generator with a rigb body and a vmn40ml stylus. A bit of a bitsa of a deck i threw together just because. Has an intermittent fault with speed stability, so some tlc is required

The JBE/SME/Dynavector sounds like a wonderful recipe.
The Roksan is where it belongs. Let the bloody thing sag some more.

Nah it wont sag now, it has has the plate clamped straight and then steel pins bashed in (literally) to correct it. Does sound nice though

In laymans terms for an ignoramus what does the compliance of an arm mean, and can I make a correct compliance magnet and fisherman chord chord arm to satisfy the compliance requirement of my spu. Havent got the sovs to pay for an spu arm. And I just know my Mayware wont pleasure the spu and by the time Ive set up the maywell Im sure to have untipped the spu after my stroke.
I should own up that last time I used the spu was on the Mayware, probably 15 years ago after Darren had supplied a Slatedeck for my 301. It sounded great but something tells me it was just wrong puting an spu on a Mayware. Not to forget it was held on with blue tack.
the mayware is such a faf to set up, post stroke Im not trusting my left had to play any role on such a gorgeous cartridge. As setting up an arm like a Mayware involves two skilled hands ….. maybe try the magnet method. With twisted fishing chord for anti scate. Jobs a lot sim0ler than a Mayware.

Meanwhile I have my trusty Ortofon MC25FL but the tip looks worryingly possible not present. So I ordered a £15 Chinese usb microscope but the driver is on a disc and my laptop doesnt have a port. I tried searching on line but Im especially Microsoft illiterate. So I acnt get anything about it to work. So Ive forgotten that and ordered next a @100x microscope that doesnt have to mate with a Microsoft computer . How anyone tolerates microsoft I have no idea they are the clumsiest idiotic platform that could ever have been built on. They should have thrown it away years ago and started a fresh. Probably when ai takes over properly it will start by putting Microsoft in room 101.
Until I can see a stylus Im scuppered.

Compliance is a measurement of the cartridge and not the arm. In simple terms, a low compliance cartridge has a stiffer cantilever and works best with a high mass arm. A high compliance cartridge has a very softly sprung cantilever and works best with a low mass arm. Very general advice, I am no longer an expert but I do remember my cartridge matching days.

Although the £50 unknown but new mm cartridge in sme headshell with litz wire came alive last night on a Ralph Mactell LP. Wow what a good tone ? Only 50 pence in charity shop so I splashed out another 50pence for Gracy Fields. Havent tried that lp yet because Im listening downstairs on the celestians to the Radio 3 concert from that place in London which my stroke wont allow me to remember the name of its almost filtered up but not quite. I wouldnt care but I delievered there tons of times as a despatch rider. What a stroke does is rob brain cells. Veryvery naughty. Anyway I like the concert. Top bananna and no sibilance scratches or warps.
Barbican.

I guess the spu has a pretty stiff cantilever being it wants 4grams of force pushing it into the groove . Maybe that much weight will save me from the sibilance that is bugging me.

Anyway so for now my hope is that the MC25 FL turns out not to have lost its tip and its probably suited to the Hitachi arm. I have to say I like the dd transport just as much as the 301. So the 301 is resting. Cartridge again, in mothballs I have a hifonic low output mc cart but one coil must be broken. Doesnt need a retip though. But who to trust with a rewire? Possibly not worth the cost. Great shame so very low output but oh boy so delicate so so minute detail, impossible to describe, but digital media would miss 80% of it.

I always found the "Cartridge Resonance Evaluator" on Vinyl Engine incredibly helpful for arm and cart matching. All you need is to enter the effective mass of your tonearm and then read the table according to your cart and mounting hardware combined mass. www.vinylengine.com/cartridge_resonance_evaluator.php

Reference the 301 vs direct drive experience. About 10 to 20 of us gathered for a weekend about middle of the country maybe 2008 or so. I took my 301 dinavector DVXX1L before its first retip. Some brought 401’s. I dont know what cart the other people brought or what arms the 401’s had. The dd’s probably had the gymble bearing arms. I had the Mayware, which worked very well on the 301, this was pre- Slatedeck, and I cant recall the pre slate plinth. Wood of some sort.
We played the Wall to death over two days. All the direct drives sounded just as good as my 301. This is only my opinion. The 401’s all fell short of the 301.
This experience backs up my confidence presently of the Hitachi Direct drive, with it’s own arm. Also is why the 301 was a bridge too far to set up again. I had lent it to a friend to build plinths so he had a 301 pattern. Did you know by the way there are two 301’s and I dont mean the difference between grease and oil, and the change didnt occur at that time. There are two castings. The earlier casting is fuller. I know this because when Darren had a slatedeck made for me when my casting sat in it there were gaps, I could see daylight. Thats how it was discovered. So Darren found another 301 with the same casting as mine and sent me that slatedeck. It filled the gaps; excluded the daylight.
Anthony who was using my 301 as a manakin, sent it back in one of his plinths for my trouble. No disrespect but I would want it back in my second slatedeck. So there is quite a lot of faffing around to restore where I have come from. But Anth is a great friend and it was a pleased to help him out.
My 301 was found at a Radio Rally. I asked; “What do you want for that old deck”? I cant remember the number, but less than £200, maybe £150. Payed up put it in the car straight away before he changed his mind. Very glad.

Decent direct drives sound better than most belt drives, too.

I totally agree Martin with that statement. With the exception of the michel gyrodeck I owned in a marble plinth. It did stuff in the top end which the 301 missed, but the 301 in the bass the gyrodeck missed. I sold the Gyrodeck but am now picturing Bazil Faulty smacking his own bottom. Why did I let that go! Sometimes we have done stupid things.

As we age though the top-end goes awol so the 301 becomes your weapon of choice. 😀
As for a bottom to smack, that would be Polly’s…
