Hello to all on this forum especially old friends BF and the Keeper   Hope you are well and it's good to see this place is ticking along nicely. 

I don't spend much time on forums anymore but still maintain an interest in all things hi fi and Sansui. Now and then I'll add a piece to the collection. So I have a question about the BA-F1 I got recently. What are the part numbers for the output transistors and output caps? For own piece of mind, I just want to check that what I've got are original.

Appreciate it if anyone has this info.

The caps that are in there are Elna ce-w 63V 15,000uF Black-neg.
The transistors were very hard to read. I could more or less make out two of them. One was NMC1002 96Y and the other (partial) number MA1216 05O.

thanks muchly
Jack

Hi Jack
Long time since I heard from you. I guess you have lovely day's in Australia during summer time.

So you have got a BA-F1. It's one of the best Power Amps from Sansui.
The output transistors were special made by Sanken for Sansui.
The name is NMA-1012 and NMC1012 but extremely hard to find.
Can be substitutet with 2SA1116 / 2SC2607 or if you can find NMA1216 / NMC1216
Have a good time Jack

Hi Jack:
 
Wow, its been a long time, I am really glad to hear from you!
 
And what a coincidence, I also got a BA-F1 recently. I wasnt intentionally looking for one, but I happened to be browsing on Ebay and I noticed one for a reasonable buy-it-now price from a reputable seller, so I decided to go for it.
 
I had always thought of the BA-F1 as sort of a power amp version of an AU-919, but since I already have two 919's, (as well as two pristine BA-5000's, and a B-2301), I didnt know if getting an F1 would be necessary.  However, as I said, the bin price was good and I'm sure if I passed on it, someone else would have surely bought it.
 
I checked some vintage hi fi mag reviews I have on the BA-F1 (such as Audio Magazine March 1980), and this amp was given very high ratings for construction and sound quality. After hearing it myself, I must say, I have to agree its a great amp. Now I'm wondering if I should look for the matching CA-F1 preamp if I can find one for sale.
 
I would also like to get a pair of rack handles for the BA-F1. I thought I could use some that I already have but I noticed the F1 has a bit more height than the 919/717, thus those handles wont fit.
 
Regards,

Hi Keeper!
Thanks for the info. I'll have another look tonight but probably one channel is original and the other has the replacement NMA1216. That would also explain why the white grease aroung the NMA 1216 is all messed up.  As long as these are good subs, I'm guessing I shouldn't worry.

Hi BF!  The basement must surely be overflowing!  Like yourself, I thought the  BA-F1 was just the power amp section of the AU919 but looking at the insides, the design seems quite different. 

I've only had a brief listen to the CA/BA combo so can't really say much about how it sounds compared to the 919.

Keeper, we are in the first of four days of 40+ degrees C. Everything is about to melt down!

Stay well guys.

Jack
