Wow. The grammar police is out...
Those resistors are ±10 % tolerance as indicated by the silver tolerance band at the end. It's been quite a while since ±10 % was used in mass production so I'm thinking these resistors are probably generic carbon film resistors. You can replace them with anything. I'd go with metal film these days, but, honestly, any resistor will do for those. I don't know which company manufactured them but I hope this information is helpful to you.

I tried to be helpful.@wik's a very respectful member.I'm not native with english.It can help anyone.I use google translate myself from time to time when I'm unsure how to spell a word.I just saw a topic where Cal expressed his opinions along these lines too....

I saw many people looking for those resistors in old equipment to use them in guitar amplifiers.They like something about them...not sure what it is though.It might be the higher noise that hides some distortion characteristics .It may be the way they dissipate heat...
I take grammar lessons anytime from a native speaker so please do it when you feel I don't spell it well!

My native language is not English. I started learning English in 5th grade. 😉
The old resistors people often like is carbon composite resistors. They're quite awful actually. They have high 1/f noise and high excess noise. I'd imagine their temperature coefficient and possibly voltage coefficient are pretty horrid too. But that doesn't stop people from seeking them out.

It's very difficult to argue against a musician choice though...A musician listening to his instrument 4...7 hours/day/10...20 years have very different ideeas about how it should sound than a technical standpoint of view where we judge an audio equipment by its noise, distortions, etc...I started french in 5th grade and english in 6th grade, but learned most of my english after I have finished my 10th grade...20 years have passed since then...forgot most of my french although I used to be vastly better at it.Audiofanzine should have been my forum 20 years ago 🙂

Yes and no. Musicians are human too and have biases and such. They also have opinions and preferences. That's alright by me.
My proficiency in English really took off when I moved across the Atlantic.

please ask at this store, a variety of resistors are available : https://www.tokopedia.com/musecomp/product/page/2 (google translate, i don't know eglish)
On my monitor, the tolerance band looks gold, which would make them generic carbon film resistors with 5% tolerance. From the size, I think they are 1/4 Watt types. They should be available from any parts vendor, and they are about the cheapest leaded resistors you can get. They are made by many manufacturers and they all look more or less the same, so it is impossible to exactly identify them from a photo. However, any 1/4W carbon film resistor should be just fine.
As others said, these are carbon film resistors, typically used in equipments from Asian origin, like Hong-Kong, Taiwan, etc. during the late sixties and the seventies.
They are generally OK, but not very stable or accurate, and have a non-negligeable excess noise, which is of no importance in most cases.
More annoying, they can sometimes fail open, especially when voltage or heat-stressed
