RCA65372 cross?

[drewl]

Anyone know what these T03 NPN power transistors cross to or the specs?

Can't find the datasheet.
Thanks.

Most seem to be using MJ15024 as a replacement. Actual cross is supposed to be RCA-1B05 which you should be able to find datasheet for.

[drewl]

Hmmm, only 2A Ic?

Strange, they were in a big power amps, only 2A?

[g1]

What is 2A? MJ15024 is 16A 250V.
What amp is it being used in?

I deleted my last post, new phone I don't know how to use!

I have a bunch of matched rca65372's I found and was wondering what I could use them for.
But they are only 2amp devices according to your cross reference.

Having no idea what you found them inside of...

Were they wired as drivers in a row of outputs?

I am guessing the 65372 is a house number, so you won't likely find a data sheet for it.

A quick google search finds it was used in Cerwin Vega amps, and from descriptions as a driver.

Ding!
We have a winner!
A Cerwin Vega carcass someone gave me long ago.
Five per channel.
Probably not worth using in anything.

Some of those CV power amps were made for them by BGW, who afaik also made amps for Altec Lansing and ElectroVoice. We do have a BGW expert here, ping nevetslab.

If you tackle solid state amp repairs, don't throw those 65372's away. They may come in handy for an old Peavey or whatever. They don't go bad with age, and 10 of 'em don't take up much room. The only problem I anticipate, is wondering where you stashed 'em comes a day you want to use them. Or flog 'em on Ebay, somebody's bound to bite if the price is cheap enough, get you some beer or ice cream money.

Ah! Refreshing. A man with his priorities sorted "correctly"

Once upon a time I did have the list of in-house numbers...or rather it was in the BGW Engineering files, until a 'brilliant' new head of the dept came on board and threw out ALL PAPER FILES, claiming that if all important data isn't already in a computer or drive someplace, its' not needed. Duke Aguiar might recognize the number...he was their Chief Engineer during the time when we were getting parts made for us by both RCA and Motorola. I'll have to see if I can track him down.....I need to get all my manuals back from him anyhow...they should have been scanned into his database long ago by now.

Hmmmmm.....5 pairs per channel on a Cerwin Vega amp, eh? Wonder if they might be RCA 1BO5's?

I just found this Peavey Cross Reference List on-line:

Peavey_Transistor_Cross.pdf

At any rate, looks like some good data in this file.

The 2A on the datasheet for the 1BO5 is base current. Ic is 7A.

The strength of those old RCA parts is that they can dissipate full power out to about 150V without hitting the second breakdown limit that most power transistors hit at 50V or less. You gotta use lots of them in parallel but they make one tough amp.
