Default Linear Systems LS302, LS313 and LS352

Hi All,

Is anyone interested in these devices?

Tightly matched VBE, hFE monolithic dual transistors, perfect for LTP/CM.

LS302
LS313
LS352

Minimum order quantity is 25 of each, so that's the target we need to reach. Prices are roughly 4.50 - 5.40 (to-71 case) plus delivery.
If there is enough interest I will get a final full quotation, based on how many devices are required.

Please list you name, device and quantity.

Interest only at the moment.

I have organised a GB for the LS313 and LS352 on another forum before, just to give you a little confidence

Hi Will
Please put me down for 4 each of the LS313 and LS352.
Alex (SandyK)

P.S.
As part of the original GB in Rock Grotto Forum , I am using these metal can closely matched dual transistors in a 15W/Channel Class A amplifier, a Class A preamplifier, and a Class A Headphone Amplifier. with excellent results.

And me, please.

I'll get back to you offline with the numbers required, as I have some in stock already.

Many thanks for organising this!

Hi Will,

A little dicky bird tweeted this GB to me by email and that for a Class A HA build I'd need 2 each of LS313 and LS352. Hope a few more folk hop on board to get the numbers, and onya for taking this on.

cheers..jeffc

I'll have 6 of each please, that's the 313 and 352. What's the LS302 for (in case I'm missing something!)

Hi Syd,

It's a potential alternative for the LS 313, with higher hFE, just in case we could find 25 people who want to try it

Cheers,

Will

Hi Chong,

They are around 4.50-5.40 each plus delivery, so 20-22 for a set of four.

I'll confirm exact cost when exact numbers are known.

I'll be closing this GB on Friday, so that we can get things rolling

Excellent! So for the mono SC class A HA, we need a set of 2 LS313 and 2 LS352, right? I have not read the BOM. If is, I will order a spare set just in case. That is 4 LS313 and 4 LS352. I will drop the LS302 due to Alex's comment at Rockgrotto. Thanks.
