After my first foray in to DCC territory with two dcc600’s and two dcc170’s
Today I managed to buy a DCC900 and a DCC951 and 16 tapes, 5 still shrinkwrapped.
Both are optically in pristine condition the 951 has a very minor scratch on the top near the back
and it is missing the remote and manual.
Both play without problems.
The 900 has a slow mechanism as predicted. but no dropouts, plays, records and plays analogue tape
without issues. I know this one will need a recap as all 900’s do. It’s saviour might have been that
it was stored for 10 years in good conditions.
Now the 951 is also working perfect though the remote and manual are missing.
A remote is on the way from germany.
What are the specific issues with the 951?
I just foud out the power caps have leaked. the smd ones ‘look’ ok…
How reliable are the smd ones? do they need replacing?
Or is it a solid machine that only needs service if it goes wrong?
Cleaning heads: can you use a q-tip and IPA or do i need a cleaning tape?
PS: Thanks DR DCC for the Ben Librand and FYC tapes.
I love the cute tiny DCCmuseum tote they came in!
Hi @HainjeDAF , you will find that the large power caps have not leaked, they have a glue around them - unless you are very unlucky lol. I don’t think there is an issue (yet) with SMD caps on the 951/730 machines. I use q tips and IPA on my heads, I have an old Allsop three head cleaner which I have looked at using in the past but although it is good for the capstans, it is useless on the head. Usual suspects are pinch rollers, the capstan drive belt and the gear on the fast wind motor. If you need any PM me & I will point you in the right direction.
Sorry about that I’ve checked all 3 of them, damage seems to be little, but no sound whatsoever. 2 decks had repairs done in the past, but unfortunately in 1 case only one cap, rest of the old ones are still there so… lots of work to be done!
Sure! I can imagine! I’ve got one here that looks like it allready has been recapped. But still it doesn’t work. In service mode it shows all tracks are faulty.
Now I imagine it to be an example of a skilled repairman who abandoned it because the head is blown… but than again I have no way of knowing so I just soldier on. I will place these boards in another player with the same milliamps on the head flexprint… just to see if there is life in them. I can’t measure them because them caps are all covered in a glue substance…
Hi @HainjeDAF, from my experience almost every second DCC951 (and DCC730 too) mainboard suffer from insufficient soldering, the board has often a lot of colder junctions. I check every unit I service and resolder the board, especially mains jack and RCA jacks have often bad soldering.
I know it has been used in a smoking household and has been in the attic for
8-10 years. (judging by the recordings I got with it.
But my experience with DCC so far, is that most decks need service.
And most decks have to my knowledge a lager chance of survival if proper
service precedes use.
And I find the investment worth my while.
