AMI R-2179-A power darlingtons

[lordbizarre]

Yo ! I'm ivan and struggeling with a major problem . As a electrotech I've worked several times on Wurlitzer and Seeburg amp's , but also on Rowe-Ami 's . Therefor I know that , for the ususal output power transistors the good old 3055 or the 3442 can be used .
But this time it's different : I've this R-2179-A amp , much more simplified , such as the cooling , parts , but also with some different output transistors , rectangular with three legs....
No problem to put some new ones in ...if I only would know which they are At my normal electronics supply store they don't know or recognise these Motorola Darlington output power transistors , with only this code on them : M ( for Motorola )826 302-D and E ( npn and pnp ) . This must be another Rowe_Ami code from the years back .
Can someone give me the normal transistor codes so I can purchase or order them at the store ?
So : one 826 302-D and one 826 302-E per channel , on the 402 063/6 driver output pcb board

Hello Ivan,

These darlintons are no longer available there is no known electronic/mechanical equivalent, you will need to search for Motorola MJE6044 & MJE6041.

If you get stuck you can contact me in the UK but these used transistors are an arm & several legs.

Yo Alan !
alright , thx man , don't think the're difficult to find . If not I'll contact you !
This is the first time I couldn't come up with some replacement parts , Seeburg and Wurlitzer had the same issues but I understand their point of vieuw . But I also remember ( and don't forget !) I once over payed aproximate 20 times the real value for coded transistors than they were to be found in the electronics shop . I was a young guy then and money didn't grew on trees..... ( it was with a Rowe-Ami MM2 at the time ( early 70's ) ...yes 2N3055's and so for a giant price....
greetings & thx man !!!
