And one more. There is clearly four figits on the screen, "T" on the left, then the two illuminated for the "AU" but then there is still one, which doesn't seem to be used in any function. Is that normal?

Have you tried other sources? CDV springs to mind.Or possibly Tape 2 (TP2)

My recollection of green displays comes from the very pair I saw when they were introduced. The display was very different from the Mk3. However I see very few Mk1s so am perfectly happy to accept that Mark 1s had an orange display!

I tried every source I have in my setup (BC9000; tape 1/2, cd, phono, aux, radio).

Tape 2 is indicated with "TP2" and that uses the first three digits from the left. The last one is never illuminated. What is CDV?

Video CD = DVD these days! What about radio presets? P12 maybe?

Of course!

I had only 8 FM presets. I quickly added some more and yes; the last digit shows the last number. Great. 

I have only listened less than few hours but I think these are real nice speakers. The high-end is not perhaps quite so bright. Could be a cross-over/cap replacement- matter? There is certainly a lot of bass, even at the linear setting of the Penta. 

They are designed to be listened to sitting down. That way, the tweeters are at ear level. It makes quite a difference! They are not as bright as 8000s for instance though.

I also noted that the high-end is best on the sitting level. 

I am anyway going to have some more research, then open up the thing and clean things, check capacitor values and later on replace them. I am going to just refresh things; I am not really interested in making modifications to the circuitry. (Well, if there is something easy to do; I just might give it a try while there :)

I am not sure yet if I will have too much worries about the midrange speakers, I think I will let them be for now. (Is there anything I can do to temporarily fix the one that has been broken? Glue the crack?)

Bypassing (shorting) the tweeter resistor is easy enough and helps slightly to get rid of the "muffled" high range. If you're not sure, it's easy to jump the resistor temporarily with a length of wire. IMO, midrange seems to be the biggest single problem with Penta; it's mellow, allright, but has a slightly nasal tone I'd love to get rid of. With classical music I like these speakers very much, listening to jazz is... well, painful.

That was the one thing I think I will do. Simple enough and reversable if needed. And yes, anything that makes the high range better is worth doing. Perhaps Die_Bogener and other experts might give us some tips? 👍

If I were you, I would refoarm the midrange speaker!  and about the cloths. the one's I saw was black. but I'm no expert on that 🙂

 Talk to Medogsfat or Dillen 🤒
