It is the first report I have of rail problems on a Sony tape (also a Type IV!). All my Sony tapes do not have rails, even those mistreated when I...
That might be a good point: my headphone is designed for modern low power devices such as smart-phone and the typical volume level I use on the...
The DD33 has been serviced by Marian and, according to him, it is perfectly fine (PB levels are perfect for Dolby decoding); I adjusted the tape...
After checking Marian guide on how to repair a DD I was surprised by the number of things that can actually break in. Even if in good condition a...
Yes, a power supply is a voltage generator which will keep the output voltage constant supplying up to a max specified current; you are not force...
typical current for DD30 is ~ 70 mA, with ageing it can go up to 100 mA, but it is quite far from 1 A. Double check polarity of the plug, for...
I think I tried everything I could to increase the HF response: I have a 10kHz test tape and I spent a couple of evenings last summer with an...
Following Techmoan video on walkman’s I too have started re-considering walkman’s outside of the DD line. When I re-discovered my interest in...
Excellent guide, I never considered how many things can brake in a DD walkman ! Actually I think you are a bit too "scary" on the tape path...
I got that tape with a batch of used Sony tapes (which are indeed fine) so I do not know when the rails developed. I have rails on other TDK...
If you check the tape surface it should appear smooth; a rail is line you see on the tape surface as if the tape had been folded. It is actually a...
The head flat cable is attached to the PCB with a tiny adhesive strip; I did not desolder it, I just let loose the cable so that the PCB can be...
That walkman should have the same tape transport as the WM-190 I tried to restore. To access the fly-wheels and motor you just have to desolder...
my 2 cents, it is better to have each thread set as sticky in its related forum; if there are too many sticky threads in the tech section, you...
The guide is excellent, but indeed incomplete: can you upload the pdf to an on-line host (sendspace, google drive ...) ? If it is too big, make it...
The same tape transport of the wm-ex402 has been used in several models, that is indeed true ! As a matter of facts, I could not find the service...
Recently I bought off ebay this 1998 Sony mid range walkman, the WM-EX402. [ATTACH] In 1998 Sony released a whole range of WM-EX40x walkman’s...
Doublecee, could you check the DC bias on the IC101 and IC201 on either a WM-3 or a TSP-L2 with the delay problem ? With a voltage meter, just...
Just for fun i tried to investigate the issue and reported my findings in this thread...
My AIWA walkman needing recapping is from 1994, but there was actually no leak, they have just dried out and capacity was null. The DD1 is from...
