Thanks for all your input Sweetbeats and all you other guys - much appreciated, as ever.

I'd also like to hear that! I guess the very low noise of the 244 made me wonder about a 16 track. I could live with 6-8dB or so more noise as a result of the extra tracks - would still be inaudible in my book. Freq. response would be the same (better if at 7.5 ips) - crosstalk would be the...

Glad you said that famous beagle. I think the S/N of the 244 is phenomenal - you can't defeat the dbx but who would want to? (made my own switch for track 1 for tape sync). Biased up for type 1 tape, dbx artifacts virtually disappear too. Freq response is 0dB at 40 Hz, flat to 16kHz, -2dB at...

Just found out that Technics made a deck - RS-AZ7 - with a thin film playback head: Technics RS-AZ7 - A full & detailed review!!! - Tapeheads Tape, Audio and Music Forums seemed to have some nice characteristics and low crosstalk.

Thanks for these responses guys and for all the figures Sweetbeats. I was wondering if a precision head (or couple of heads) could have been fabricated using thin film techniques? I think the crosstalk figure for the 238 is around 70dB - I guess for a 16 track set-up with the sort of guard band...

A bit a a rambling post I'm afraid but I'd love some comments on this! I'm always amazed how some cassette multitrackers can sound - still very happy with my Tascam 244! When cassette 8 trackers became available it seemed unbelievable at the time but they also seemed very capable in good hands...

Hi Level Anything. As nobody has replied I just thought I'd mention that I thought one of the motors had stopped working on one of my 244s, only to find they had seized up as a result of the belts turning to gunge. Worked fine after I had cleaned up around the shaft. I guess you tried his...

Hi Cjacek. Yes it was me re-biasing the 244 for Type I UR! Works magnificently. As I understand it, bias does need some adjustment at different speeds as part of the compromise between freq response, output, dropouts etc. Pros refer to amount of overbias needed at different speeds and it can be...

Just thought I'd mention that when you adjust the speed trimmer on the 244 from the central indent you may get increased w&f - Sweetbeats pointed this out to me a few months back when I was going for max speed. I liked the slightly enhanced top response at max speed (about 4.5 ips?) but found it...

Have just fitted the diodes to the supply rails and seems to be working well! Have put the LM4562 back in after initial trials with NE5532s. It is fabulous to have a tiny battery operated pre for condensers. I don't need the That 1510 in this amp as the signal from the condensers is so great...

Thanks again Dave. I will start now building the supply diode design. By the way, can I remove the 22k resistors to earth after this or should they stay?

Dave - would it work if I just put a diode from each input, just after the blocking capacitor on your original circuit to earth? Or is it much better to stick to the pair of diodes to the supply rails?

Thanks again Dave! Would 1N4007s do? Maplin don't seem to have the 1N4008. 1N4007S 1A Silicon Rectifier | maplin I've heard people talk about using Zener diodes but surely you just need ordinary types?

Thanks for this Dave - will look at the link in a minute. Meanwhile, have had a few problems with the phantom power frying the chips! Would some diodes protect the input? Any suggestions?

Just thought I'd add a reminder that I found that my 244 works sounds fantastic using UR after the bias has been re-set for it. I get none of the dropouts and strange effects I often found with type II. Recalibrating Cassette Format Portastudios to use Type I Normal Bias Tapes

PPS have just built the final version using 4 A23 batteries to provide the phantom power. It sounds great with the BM - S/N is way better than using the pre-amps in my Tascam DP recorders. Just noticed that the polarity of the BM is inverted though and will have to rewire it.

Dave - I've just made a lash up of this circuit with the suggested resistors and it works a treat! I first used 2 9V batteries and was getting some hiss with the BM and some intermittence with a Sontronics ST-20. Using 4 batteries (36V) both mics sound great. I'd like to get away with 4...

Thanks so much for this Dave. I am away from home at the moment so just got time for a quick thank you. Will post more next week when I am back.

I've just bought the BM-800. It is amazing value at £12 and sounds as good as my Sontronics ST-20, with higher sensitivity. Over 14 micro Volts/Pa. Dave- would you know if it would be a simple mod to power up this mic with a couple a 9V batteries rather than using phantom power? I'd like to...

Hi Steenamaroo! Thanks for your help on this. I'll check the cables too. I think I'll leave the tie to ground off for a while to see how things go. It seems to have removed some (very low level) hum so I think the balanced operation is working! Thanks again for your previous help with the...
