Description
Tube phono-preamplifier
- Improved version of the Phono Box S
- Valve output adds more analogue warmth
- Widely compatible with MM and MC cartridges
S-Line
The Tube Box S from Pro-Ject Audio Systems offers un-rivalled performance, exceptional sonic ability and unique flexibility for a very competitive price.
The dual-mono configuration, audiophile amplifier modules and polypropylene capacitors allow for a dynamic soundstage with ample detail; yet the addition of two ECC83 valves (one per-channel) adds new life and realism to the musical performance. The sturdy casework and external power supply further help to reduce the effects of outside interference, like other models in the S Line, but the Tube Box S also externalises its valves for optimal heat dissipation.
Where the Tube Box S takes another step up in ability is in its various setting adjustments. Using the dip-switches underneath the chassis (there are two sets - one for each channel), it's possible to more accurately match the turntable cartridge's technical characteristics. The dip switches allow for various Gain, Impedance and Capacitance settings. The built-in Sub-Sonic Filter further helps tailor the sound, rolling off any problematic rumble that may appear underneath 20Hz.
The sonic quality of the Tube Box S is extremely impressive and offers a notable improvement over any other S Line phono stage, making it an audiophile upgrade for almost any mid-priced analogue hi-fi system.

We are an approved retailer for all brands sold on our website, which means full manufacturers warranty and support as well as detailed product knowledge within our small business.
We use an inventory tracking system which states if item(s) are in stock and if not, what are the likely lead times.
Selecting "Next Day" delivery does not mean you'll receive your item the next day in some cases. It's the next day from when the item(s) are in stock with us. If there is an urgent need then please contact a member of staff via the Live Chat or telephone (01757 826111) to check on live stock levels.
We do ask for some patience during lockdown - we're working remotely from home and travel to the warehouse each day to fulfil orders. If item's aren't in stock - we can usually get them within a couple of days.
We're a small business that's been impacted massively due to COVID-19 and have such had a significant reduction in orders. We're focussing on core products and services with less frequent products being ordered "on demand".
When will orders be dispatched?
- Orders placed Monday - Thursday before 2pm and are in stock will be dispatched the same day for next day delivery. This relates to product that state 'In Stock for immediate dispatch' on the product page.
- Orders placed on after 2pm on Thursday or on Friday will be dispatched for delivery on Monday unless Saturday delivery is selected.
- Orders placed over a weekend and are in stock will be dispatched on Monday.
Orders for items not in stock
Given the vast amount of variations of each product (e.g. AudioQuest cables) or Pro-Ject Audio Turntables - we keep the most common options in stock (i.e. gloss black finish, or 1.5m RCA cables) whereas longer cables or cables with terminations that are less frequently ordered will be ordered as required.
Generally speaking - we receive orders within 2-3 days for UK suppliers and 3-4 days for European suppliers (i.e. AudioQuest, DALI).
We want you to be 100% satisfied which is why we'll give you an email/call if item(s) aren't in stock and give you the option of changing the order, cancelling or if you're happy to wait a few days, we'll get it out as soon as possible.
If an item states 'Available to order. Usually dispatched within 48 hours' - this means the item is not in stock but we are able to order in. Lead times average 2 days but in some circumstances, delivery times may be longer and is outside of our control. Please contact us to get an estimate on delivery times if orders are urgent.
Who do you use for delivery?
Our primary delivery agent is DHL. Where orders are shipped directly from Yorkshire AV, we always use DHL who offer a fabulous service at competitive rates.
If we drop ship (i.e. direct from the supplier) then the delivery agent is out of our control. It is generally DPD or UPS however - we rarely see other carriers used.
