Telefunken M 15A input cardboard circuit.

Quoted from "stereofonic" I attached two photos of the BC-AV card of my M 15A. Thank you! This one should do it: Cheers, Peter

Telefunken M 15A input cardboard circuit.

Quoted from "stereofonic" I search the electric design of the input cards with number 25.5069.065-00 ... This card has several versions with the same ID number. Could you please send a picture of that card, both sides? Thanks! Peter

Quoted from "M28" Um die Schwungscheibe des Capstantriebs zwecks Riementauschs korrekt auszubauen benötige ich eine Anleitung, damit ich nichts kaputt mache. Voilà: https://we.tl/t-xXUWBG8USS (Link gilt 7 Tage) Die Anleitung ist auf pdf-Seite 58. Grüße, Peter

Welche A/D- bzw. D/A- Wandler benutzt ihr ?

Bei mir sind es zwei RME Ficeface UC und ein modifiziertes Behringer ADA 8000. Beide sind rein klanglich nicht voneinander zu unterscheiden, allerdings "kann" der Behringer nur bis 48 kHz und rauscht ca. 10 dB mehr, was in der Praxis aber keine Rolle spielt (ca. 103 dB Rauschbstand im AD-Teil).

Telefunken M5A

Hi Evert, I don't know the meaning of "SLC", but the T2-H7 should work for 1/4" tapes. Apparently is was designed originally for Umatic recorders. This offer is not exactly cheap, I might add I'm using a T2-H12-X 340G, and it works perfectly fine, and I still don't know what "X 340G" means. Unfortunately, Tentel's website is now offline for some time and I couldn't trace it via wayback machine either. You'll find an instruction manual for these in the attachment, just in case. Good luck, Peter

Hi Evert, Quoted from "Evert" Then, also (fast) forward function is too slow. Do you have any clue what could be the problem? Hard to tell without further details. Could be more than just one cause. Have you checked the tape tension on the both sides of the capstan? Also the pinch roller pressure? Best, Peter

Bandgeräte im Film

Quoted from "Bandsalatvorkoster" Auf den ersten Blick sind mir keine "epochalen" Ungereimtheiten aufgefallen. Nun ja, auf einer Nagra III 1960/61, die filmuntypisch mit 38 läuft, aussschließlich Uher-Aluspulen zu sehen, zudem noch paarweise ... da hatte ich gewisse Fragezeichen auf der Stirn. So schwer sind zeitgenössische Kunststoffspulen von Agfa oder BASF doch nicht zu bekommen, oder? Und für Reportagedrehs Fiberglasangeln zu benutzen, noch dazu mit einem dynamischen Nierenmikrofon (MD 421) ...

Telefunken M5A

Quoted from "Evert" Is is easy to change a playback head? It depends. I only know when I have the parts on my workbench. According to Telefunken documents (see pictures), AB01 and WB01 are replacement types für M10 and M5C. How the heads were mounted into a M5 headblock has changed simetimes over the years, so I can't really tell. But I have managed to mount newer heads into older shells every time so far. very probably you will need some discs for height adjustment (0,05 - 0,1- 0,2 mm), but th...

Telefunken M5A

Quoted from "Evert" Again, I couldn't get enough "highs": at 10Khz /-20 db I measured a deviation of more than 18 db (18 db less output than the signal on the calibration tape). This would explain, at least in part, why the recordings made on the M5A sound too sharp on other machines: The "Höhen" EQ of the recording amp is too strong because you adjusted it for linear reproduction on a reproducing head with too much gap loss. Quoted from "Evert" Could be a worn playback head? That's very likely...

Telefunken M5A

Quoted from "‘Evert’" I attached a picture of the playback head and the recording head. First of all, the playback head looks quite worn to me, with the gap region at the end of its lifetime. In addition it has still the original ring form. Heads for replacement (so-called long life heads) look somewhat differently, more like the ones for M10 and M15. Quoted from "‘Evert’" Can you tell me where I can find the azimuth screws on both heads? The azimuth screws are underneath the small cover plate ...

Telefunken M5A

Quoted from "Evert" I don't know how to check the azimuth (I have to look this up. I have a leader oscillopscope which I think I must use). If your M5A is a full track machine, you would just need a VTVM or some similar. You first playback your reference tape at the slowest speed and adjust the playback head azimuth at 1 and 10 kHz for maximum output level. Then you adjust the recording head in the same way, using a relatively unused tape with the same speed and frequencies (or white noise, if ...

Telefunken M5A

OK, could you please quantify the deviation in playback response of the reference tape for the different frequencies @19? And did you check the azimuth alignment for PB and Rec? The fluctuation could be caused by a lack of alignment between recording & reproducing head. If it's not, things might get somewhat complicated. Peter

Telefunken M5A

Quoted from "Evert" I just can't get enough 'highs' (treble) whatever the setting on 19 cm/s (VM, Hohen I-II, pegel, WV/AV). Did you check the playback frequency response with a reference tape or something? Could be a worn reproducing head which is not yet noticeable at 38 speed. (Please also consider that you might have got a machine with 100µs EQ at 19.) If anything, I would expect an unmodified M5A to produce too much treble because the M5A EQ circuits were designed for tapes whch were much ...
