...why was almost every speaker made ...back in the Day 4 ohm....
It's cheap. Fewer turns. Enough Ohms that the part-Ohm of the lead-in wires does not matter. That's good when speaker is in the same box as the amplifier (very short wires).
The alternate was 15 Ohms for when wires had to run across a large room. Less line loss.
In smaller US talking-movie theaters the next step was two 15r in series for a 30 Ohm load which gives low line loss across medium large movie theaters.
8 ohms used to be the odd duck. But that happened to be a good V/I ratio for the early transistors.
You can run ANY impedance the system is designed for. There are compromises when you get way out. The speaker lead-in tinsels are say 0.4 Ohms. If you wind a 2-Ohm voice coil then 17% of your precious power is wasted in the lead-ins. (However today there ARE 2-Ohm car woofers, the good ones use an extra-heavy lead-in tinsel.) Up around 600 Ohms the coil winding wire wants to be thinner than the enamel insulation, so you use thin enamel, but moisture gets through, rots the thin copper, speakers don't last forever.
Here is the schematic

I dont care if the FM is not hifi all i want to know is that if i use tape input if it will sound good or not.

I would need some convincing Astouffer .
FLAC - Wikipedia
"FLAC (Free Lossless Audio Codec) is an audio coding format for lossless compression of digital audio,
"The compressed files are always perfect, lossless representations of the original data."
If you follow the math, you can verify that output==input.
You may still "hear a difference"; this is always an option.
As I said, the amp has some pretty aggressive compensation to knock down high frequency response.I dont care if the FM is not hifi all i want to know is that if i use tape input if it will sound good or not.
wait is he right if he is then i have to find another tandberg radio what about huldra 4 to 6.As I said, the amp has some pretty aggressive compensation to knock down high frequency response.
Look Fjellreven its a pretty upmarket circuit ---for its day as a table radio but it is not comparable to the 1970/1980,s dedicated tuner/amplifiers which could reach 15Khz .
Its down to circuit design of the time , its very good as a table radio .
In the Huldra 8 you will notice they redesigned the FM tuner .
Actually the Huldra 5 would be a better choice .

Yeah i own the huldra 8 im a little bit dissapointed the huldra 7 cant keep up but oh well i guess the transistor radios tandberg made were better then their tube radios. The huldra 8 sounds Great with some 70s seas speakers like the hifi kit 30.
Also great as tabletop radio with speakers that sucks and only 5 khz on the tape input. Yeah and im serious those goodmans speakers are terrible. The regular old tandberg type 165 could beat them easily.
Also i dont expect every tube radio to be hifi its just that i expected a little bit more since its a huldra.
Can the huldra 5 reach 10 khz on the tape input.

Even the Huldra 5,s own graph shows at 9 khz its -30db down .
Most of Goodmans UK loudspeaker output was in low grade loudspeakers in table radios in the UK with small voice coil magnets they were never made for hi-fi .
Even Goodmans "hi-fi " range were for those who couldn't afford something better but in the ,50,s they made some passable loudspeakers for industry ,they also made hi-fi loudspeakers in the ,70,s but be aware they were never near the top end in audio reviewers eyes.
Having said that I have a pair of Goodmans Magnum -K2 -M-range late ,50.s/early ,60,s loudspeakers the 12" driver and the mid and tweeter seem to be very collectable .

Yeah i own a tandberg hifi system 11 with a 5 inch goodmans speaker and a 2 inch tandberg tweeter i think its sounds awesome much better then the 5x8 goodmans in the sølvsuper 8.

I posted this in the appropriate forum. https://www.diyaudio.com/forums/pc-based/356705-comparing-compressed-flac-files.html#post6259902
Can i extend the leads to the reservoir cap one of them is a 17 uf film capacitor and its leads are too short.
You would be better with a sleeve of some sort or a small electrical connector as I have watched various types of electrical insulation tape deteriorate over years due to heat.

Dielectric thickness is directly related to physical size and inversely related to leakage current and capacitance. So I am not worried. Its sonic profile may or may not be pleasing.
ts obvious you haven't worked in the electrical engineering industry N1012N---I have and changed plenty of them but as you don't believe me will you take the word of one of the highest respected websites in the land on this subject for the reference of guys with strings of letters after their names ??

The sonic profile of the electrical tape on a capacitor lead?
