mouser advice please..

[tarior]

Really? Don’t think that those that regularly rebuild this gear can’t figure out what to order from mouser.digikey? There are endless threads of discussion answering questions exactly like yours. Searching for that transistor brings back a number of threads with substitutes.

The resistor, well if it measures I wouldn’t replace it. And finding a replacement wouldn’t be difficult.

Maybe start a thread about your unit and ask as you proceed and get answers so you can order. Or use the services of the vendor to pick your parts. But I wouldn’t say folks here can’t figure it ouT.

Ya' gotta love it when someone can't identify basic components, then goes on to call everyone else idiots for not holding his hand tightly enough.

Some of us on here have probably 20 or more years of experience than the " Mouser" techs do.

Can anyone tell me the name of these parts and how do I order them thru Mouser?

I'm just a noob but I know enough to at least post a schematic, are you familiar with them?

 

[Blue Shadow]

Damn youngsters at mouser, answering questions on all sorts of issues probably a dozen years into their career.

The akers are usually well-seasoned, aged and versed in vintage audio electronics and the occasional F-15 Eagle variant and its electronic warfare systems and avionics.

Millennials and their instant gratification. LOL

We haven't been given much information but based on the pictures, I'm betting on output transistors. Looking at the spreadsheet for the 2SC789O, something like a TIP41BG would suffice and the complementary TIP42BG is available too.

if it was quasi-comp, i'd go ksd526 myself and replace all 4. but i stocked up before they went obsolete.

" Mouser" techs do.

mouser "techs" would be a better descriptor me thinks

This reminds me of an old joke. A guy flying a hot air baloon gets lost. He descends over a park and shouts at a gentleman who was walking his dog:
"Hey! Can you please tell me where I am?"
"Sure. You're in a hot air baloon, about thirty yards from the ground."
"Thank you. I bet you're an engineer, aren't you?"
"I am. How did you know?"
"Well, everything you've told me was perfectly accurate, but completely useless."
"Right. I reckon you must be a manager."
"I am. How can you tell?"
"You have no idea where you are and what you are doing, but you expect me to help. You are in the exact same situation you were before having met me, but now it's my fault".

TIP-29A for NPN's and TIP-30A for PNP's are exact replacements. Mouser is zero balance for the TIP-30A.

TIP-29C and TIP-30C are available. AT 100v versus 60V.

Fireball - What can I say.

d526 is great for lower voltages but i'll keep that in mind when i run out. i'm notafan of mje15032 in quasicomp. they work but i don't care for the sound.

they say transistors have no sound to them but i have noticed it in hk330b outputs so i won't go back. it was drastic!
