butterfly head is fine because ours head too, to play our tapes A80 is best choice because play back with same type of what used in recording, if you like to modify the repro amp as I did and will have more better result, very simple just changed the out put stage into tube (WE437A) SE, with 2.4k to 600 ohm output transformer also change all the caps in coupling path to a better quality caps that is what we using for copy tapes, you can take a look what I posted before

for another opinion, I very much dislike butterfly heads. These heads were created for the BBC so they can play both stereo and mono tapes with the same headbloc. This to me severely compromises channel separation and s/n. What you also get in return is a 3dB gain.

I´ll change pinch roller
ATHAN has a good one right?

One of my A80's came from NRK. Still has the logo on it.

Athan makes great stuff!

UHA Phase 11

 

[christensenleif@msn.com]

possible, but I can´t help feeling screwed when I look at their products as well as Sonorus....got the feeling that they´ve turned on the hi-end audio taxameter for oligarks
I also happen to think a DIY guy can make something that matches it for far less money....less the Celtic pattern...what on earth were they thinking?

The UHA Phase 11 with external PS is the real deal... A no brainer for anyone that wants a plug n play unit that comes with a warranty and top notch support!

possibly, but part of the fun is to develop and build something myself
the satisfaction of sitting down and listening to something I´ve built myself is worth a lot!
and I don´t do it to save money......

anyway;
hats off to UltraAnalogueRecordings...Rossini Duo

even on my "shitty" A807 with VU it sounds amazing
through all the dirt, it´s still easy to recognize the astounding harmonics and richness of tone

That's why I tie my own flies and build my rods, well wrap them. I don't form or glue up the bamboo or make the carbon fiber. When I caught my first trout on my own rod and custom designed fly it became a part of the Breuninger permanent memory bank.

no Norwegian viking in his right mind would do such a dumb thing...

Hey, I never understood that either. Did you know you can buy fish at the store? )

Same reason I don't hunt. I wouldn't enjoy spending the day in the woods with ticks, flies, mosquitoes, and all the rest of the critters while I'm waiting to ambush an animal that is walking by. I do all of my hunting at the grocery store and I always bag everything I came for.

Never understood hunting either. Out early morning freezing your ass off. I go "hunting" the same place you do!

Having done it in my younger days...hunting sustainable animals like deer ...it's all about the wait and enjoying the sounds of nature. I still do it, but with camera gear.
Lots of effort and stealth required to capture your quarry.

A80 Reproamp mods

hello
have inspected the original reproamps and have some questions:
a) people complain about the yellowish Frako 47µF/40v elytics....due to sound or reliability issues?

can they be replaced by bipolar BG N or Panasonic FC? do they really need to be 40vdc?

b) are the green Plesseys original? are they ok or replace by same as above? do they need to be 18vdc?


c) what about the A101? see they sell replacements on ebay...just because of failure or sound?


d) are the two cables original? replace by e.g Mogami 2552 balanced shielded microfone cable?


e) some people jump the output transformers....any ideas?


hope someone can enlighten/guide me..
thxs in advance
best
Leif

Hi Leif
First of all down load the circuit from internet , of cause you can replace all old caps with the same value but effectively to sound quality is coupling ones for those decoupling caps has to be same voltage or higher. the coupling caps is those red Tantalum better to use non polarity instead but with the same value then much much bigger in size that means you have to put it in out side. A101 is the first gain stage amp Studer made it like IC ,if replaced need calibration I keep the first two stages in stock design which will have a better frequency response (adjustable) for recording. for those short cables will not change much sound quality and even without shielding ,I use solid silver wire instead. the push pull transistor out put amp is sounding cloudy a simple tube amp with 600 ohm out put transformer can sound much better but you still can spread into two in put from second stage's out put, one way to tube amp the other to the transistor amp for a pair VU meter driving because you don't have meter in you unit
happy modification
